17 A 1.37-kg block is held in place against the spring by a 74-N horizontal external force(see the figure). The external force is removed, and the block is projected with avelocity v] = 1.2 m/s upon separation from the spring. The block descends a ramp andhas a velocity v2 = 1.4 m/s at the bottom. The track is frictionless between points A andB. The block enters a rough section at B, extending to E. The coefficient of kineticfriction over this section is 0.24. The velocity of the block is v3 = 1.4 m/s at C. Theblock moves on to D, where it stops.

5. Moumita is holding a mass m=0.50kg, which is connected to the bottom of a vertical spring with spring constant k=10.0ON/m. She is holding the mass in place at a height h=1.5m above the floor. The spring is relaxed in this condition. When Moumita lets go of the mass, how far will the mass fall before it turns around and starts to travel upwards?
A 500-g block is released from rest and slides down a frictionless track that begins 2.28 m above the horizontal, as shown in the figure below. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a spring constant of 34.5 N/m. Find the maximum distance the spring is compressed. m 500 g h
In starting a game of pinball, the 44.7 g ball rests on a spring, of spring constant k = 18.8 N/m, that has been compressed by 0.0900 m. If the spring is released, how far up the pinball table (which is inclined at 39.0°) does the ball go before rolling back down again? You can assume it doesn't hit any obstacles on the way up.
Initially sliding with a speed of 4.3 m/sm/s, a 2.0 kg block collides with a spring and compresses it 0.42 mm before coming to rest.What is the force constant of the spring?
Two identical springs, both of force constant k=200 N/m, are fixed at opposite ends of a level track. A 5.0 kg block is pressed against the left spring, compressing it by 0.15 m. The block (initially at rest) is then released. The entire track is frictionless except for the section between A and B. Given that the coefficient of friction between block and track is 0.08 and the length of AB is 0.25 m, determine where the block comes to rest, as measured from A. Give the given and solution
A glider with mass m = 0.240 kg sits on a frictionless horizontal air track, connected to a spring with force constant k = 4.70 N/m . You pull on the glider, stretching the spring 0.110 m , and then release it with no initial velocity. The glider begins to move back toward its equilibrium position (x=0). What must the initial displacement of the glider be if its maximum speed in the subsequent motion is to be 2.40 m/s ?
