Concept explainers
A mass m slides along a frictionless horizontal surface at speed v0. It strikes a spring of constant k attached to a rigid wall, as shown in Fig. 13.28. After an elastic encounter with the spring, the mass heads back in the direction it came from. In terms of k, m, and v0, determine (a) how long the mass is in contact with the spring and (b) the spring’s maximum compression.

- An inclined plane of angle = 20.0 has a spring of force constant k = 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in Figure P6.61. A block of mass m = 2.50 kg is placed on the plane at a distance d = 0.300 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?arrow_forwardWhen a 3.5 kg block is pushed against a massless spring of force constant 4.5 x 103 N/m, the spring is compressed 7.9 cm. The block is released, and it slides 2.8 m (from the point at which it is released) across a horizontal surface before friction stops it. What is the coefficient of kinetic friction between the block and the surface?arrow_forwardA block of mass ?=3.80 kg slides along a horizontal table with velocity ?0=1.50 m/s. At ?=0, it hits a spring with spring constant ?=41.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.arrow_forward
- The massless spring of a spring gun has a force constant k = 0.04 N/cm. When the gun is aimed vertically, a 40 g projectile is shot to a height of 5.0 m above the end of the expanded spring. (See below.) How much was the spring compressed initially? (Find d, in meters.)arrow_forwardConsider the following system: A spring has stiffness 598 N/m and is initially uncompressed. It is oriented vertically and placed on hard surface. A mass of size 2.3 kg is released from rest 9 m above the spring. Calculate the speed of the mass at the moment when the spring is compressed 0.5 m. Use g = 10 m/s2. (Please answer to the fourth decimal place - i.e 14.3225)arrow_forwardA block of mass m=3.53 kg is attached to a spring, which is resting on a horizontal frictionless table. The block is pushed into the spring, compressing it by 5.00 cm, and is then released from rest. The spring begins to push the block back toward the equilibrium position at x=0 cm. The graph shows the component of the force (in Newtons) exerted by the spring on the block versus the position of the block (in centimeters) relative to equilibrium. Use the graph to answer the questions. How much work is done by the spring in pushing the block from its initial position at x=−5.00 cm to x=2.20cm?arrow_forward
- The spring of a spring gun has force constant k = 406 N/m and negligible mass. The spring is compressed 7.3 cm, and a ball with mass 25 g is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 7.3 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is held so the barrel is horizontal. What is the greatest speed the ball has along the barrel if a constant resisting force of 7.0 N acts on the ball as it moves along the barrel? (Your result must be in units of m/s and include 2 digits after the decimal point. Maximum of 3% of error is accepted in your answer.)arrow_forwardHello, here is my question A spring with spring constant k = 3.75 N/cm is compressed 7.00 cm. A 1.50 kg mass is placed next to the compressed spring. When the spring is released, this mass moves without friction and collides with a stationary mass of 2.00 kg. The two masses stick together and move without friction up a slope angled at 20.0 degrees. (a) (10 points) How far along the slope does the two-mass system travel? (b) (5 points) If it takes 5.00*10-3 seconds from the initial impact for the two masses to stick together, what is the magnitude of the average contact force between the two blocks? (c) (5 points) The two-mass system will slide back down the slope and compress the spring. What is the spring’s maximum compression? Thank you!arrow_forwardm A shown in the picture, a 238 g mass slides down a curved incline then collides with a spring. The spring constant of the spring is 106 N/m. Assume that friction is negligble in these problems. (A) If the mass starts from rest at a height of 1.97 cm, what is the final compression of the spring when the mass comes to rest? Assume the spring is initially uncompressed. 2.95 cm (B) If the mass initially compresses the spring 1.14 cm, what is the maximum height the mass rises to on the incline? Assume the mass is released from rest. (C) If the mass is released from rest at a height of 1.97 cm, what is the compression of the spring when the mass has a speed of 45.4 cm/s?arrow_forward
- A 3.00 kgkg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0360 mm. The spring has force constant 845 N/mN/m. The coefficient of kinetic friction between the floor and the block is 0.420. The block and spring are released from rest and the block slides along the floor. What is the speed of the block when it has moved a distance of 0.0170 mm from its initial position? (At this point the spring is compressed 0.0190 mm.) Express your answer with the appropriate units.arrow_forwardOne end of a spring with a force constant of k = 10.0 N/m is attached to the end of a long horizontal frictionless track and the other end is attached to a mass m = 2.20 kg which glides along the track. After you establish the equilibrium position of the mass-spring system, you move the mass in the negative direction (to the left), compressing the spring 3.18 m. You then release the mass from rest and start your stopwatch, that is x(t = 0) = -A, and the mass executes simple harmonic motion about the equilibrium position. Determine the following. (a) displacement of the mass (magnitude and direction) 1.0 s after it is released magnitude direction ---Select--- (b) velocity of the mass (magnitude and direction) 1.0 s after it is released magnitude m/s direction ---Select--- (c) acceleration of the mass (magnitude and direction) 1.0 s after it is released magnitude m/s2 direction ---Select--- (d) force the spring exerts on the mass (magnitude and direction) 1.0 s after it is released…arrow_forwardA toy cannon uses a spring to project a 5.32-g soft rubber ball. The spring is originally compressed by 4.94 cm and has a force constant of 8.10 N/m. When the cannon is fired, the ball moves 14.6 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.0315 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? (b) At what point does the ball have maximum speed? (c) What is this maximum speed?arrow_forward
