A block with mass 2.0 kg is pressed against a spring with spring constant 500 N/m, compressing the spring a distance of 0.1 m. It is then released from rest, moves across a frictionless horizontal surface, down a frictionless hill (vertical height 3.5 m), and onto a horizontal surface with friction (coefficient of kinetic friction 0.4). How far will the block slide across the horizontal frictional surface before coming to rest?

A block with mass m = 19.1 kg is pressed against a spring with spring constant 2.720E+3 N/m, compressing the spring a distance of 0.130 m. It is then released from rest, moves across a frictionless horizontal surface, down a frictionless hill (vertical height h = 8.24 m), and onto a horizontal surface with friction μk = 0.287. How far (in m) will the block slide across the horizontal frictional surface before coming to rest?

A 4.00 ✕ 105 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.300 m by a large spring bumper at the end of its track. What is the force constant k of the spring (in N/m)?     Answer___________ N/m

A 1.4 kg mass slides to the right on the surface having a coefficient of kinetic friction 0.25. The object of the speed of v(initial)=2.7 m/s when it makes contact with a light spring that has a force constant of 50 N/m. The object comes to rest after the spring has been compressed a distance d. The object is then forced toward the left by the spring and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest at distance D to the left of the unstretched spring. Find the distance of compression d. Find the speed v at the unstretched position when the object is moving to the left. Find the distance D where the object comes to rest.

A factory worker drops a 10 kg steel block from rest (m=10). The block then falls 30 cm onto a vertical spring standing on the floor. The spring constant of the spring is 400 N/m (k=400). The block makes contact with the spring, it then continues to move downward, compressing the spring until it comes to rest. (The spring then decompresses, firing the block upward.) Determine the distance that the spring was compressed by the block.

The block in the figure lies on a horizontal frictionless surface, and the spring constant is 42 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 3.0 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops. When that stopping point is reached, what are (a) the position of the block, (b) the work that has been done on the block by the applied force, and (c) the work that has been done on the block by the spring force? During the block's displacement, what are (d) the block's position when its kinetic energy is maximum and (e) the value of that maximum kinetic energy? x=0 Ę = 0 0000000 Block attached to spring (a) Number Units (b) Number Units (c) Number Units (d) Number Units (e) Number Units X > > >

A toy cannon uses a spring to project a 5.31-g soft rubber ball. The spring is originally compressed by 5.08 cm and has a force constant of 7.95 N/m. When the cannon is fired, the ball moves 14.0 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 2 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? m/s (b) At what point does the ball have maximum speed? cm (from its original position) (c) What is this maximum speed? m/s Need Help?

A block with mass m = 2.20 kg is placed against a spring on a frictionless incline with angle e = 30.0°. (The block is not attached to the spring.) The spring, with spring constant k = 21.0 N/cm, is compressed 17.0 cm and then released. (a) What is the elastic potential energy of the compressed spring? (b) What is the change in the gravitational potential energy of the block-Earth system as the block moves from the release point to its highest point on the incline? (c) How far along the incline is the highest point from the release point?

A 1.20 kg block slides down a frictionless incline with a slope angle of 42.0°, starting from a height 2.30 m above the bottom of the incline. The incline meets a frictionless horizontal surface, at the end of which is a spring in its equilibrium position (k =460. N/m) used to stop the block. Find the maximum compression of the spring.
