A spring with spring constant k=600 N/m is compressed by 10 cm and launches a ball vertically into the air. The mass of the ball is 2.0 kg. Determine how high the ball will be launched.
9. A vertically mounted spring (k = 900 N/m) is compressed by 24.0 cm relative to its unstrained length. A mass (m = 0.22 kg) is placed at rest against the spring. When the spring is released, the mass is launched vertically in the air. What is the speed of the mass (m) when it passes by a point located 9.02 m above the release point? m/s
2. Maria and Rory are using a spring launcher to move a 125 g block to the top of a ramp. The spring launcher is at the base of the ramp and consists of a platform and a spring with a force constant of 420 N/m. The horizontal surface at the base of the ramp is smooth and frictionless. They compress the spring by 0.12 m with the block resting against the spring launcher. Once they let go, the block travels up the 1.4 m ramp and comes to rest at the top of the ramp. The top of the ramp is 1.0 m above the ground. Ramp Experiment Ad= 1.4 m smooth frictionless surface What is the average frictional force acting on the block as it moves up the ramp? Ah=1.0 m
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?
5. Two 8.5 kg masses are hung from a horizontal surface by two (massless) springs, as shown in the figure. The top spring has a spring constant of 400 N/m, and the bottom spring has a spring constant of 200 N/m. How long is each spring in this configuration if they both have rest lengths of 6.0 cm?
A spring with constant 56 N/m is positioned so that is sits right below an object of mass 5.0 kg. The object starts at a height of 2.9 m above the spring and is released from rest. The object falls directly on top of the spring, compresses it and eventually comes to rest. What is the compression of the spring in meters at the bottom of the motion when the object comes to rest? (Use g = 9.8m/s2 and round answer to 1 decimal place.)
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.
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 ?
The spring in the muzzle of a child's spring gun has a spring constant of 705 N/m. To shoot a ball from the gun, first the spring is compressed and then the ball is placed on it. The gun's trigger then releases the spring, which pushes the ball through the muzzle. The ball leaves the spring just as it leaves the outer end of the muzzle. When the gun is inclined upward by 30° to the horizontal, a 57 g ball is shot to a maximum height of 1.84 m above the gun's muzzle. Assume air drag on the ball is negligible. (a) At what speed does the spring launch the ball? m/s (b) Assuming that friction on the ball within the gun can be neglected, find the initial compression distance of the spring. m
