If a 4-kg block is placed against the spring and the spring is released, what will be the speed of the block when it separates from the spring at x =0? Neglect any friction in the problem.

A 0.1 kg disk is shot across a frictionless horizontal surface by compressing it against a spring and releasing it. The spring has a spring constant of 380 N/m and is compressed from its equilibrium position by 6.2cm when the disk to a complete stop. As the disk gets released from the spring, what will be the speed (in m/s) of the disk when the spring is compressed by 3.8cm?

A ball of mass m = 1.85 kg is released from rest at a height h = 74.0 cm above a light vertical spring of force constant k as in Figure [a) shown below. The ball strikes the top of the spring and compresses it a distance d = 9.50 cm as in Figure [b] shown below. Neglecting any energy losses during the collision, find the following. (a) Find the speed of the ball just as it touches the spring. m/s (b) Find the force constant of the spring. KN/m Hwww

A block of mass 3.8 kg is placed against a horizontal spring of constant k = 735 N/m and pushed so the spring compresses by 0.0550 m.   (a)What is the elastic potential energy of the block-spring system (in J)? (b) If the block is now released and the surface is frictionless, calculate the block's speed (in m/s) after leaving the spring.

A 306 g mass slides down a curved incline then collides with a spring. The spring constant of the spring is 156N/m. Assume that friction is negligable in these problems. If the mass initially compresses the spring at 0.63 cm, what is the maximum height the mass rises to on the incline? Assume the mass is released from rest.

A 13 kg runaway grocery cart runs into a spring with a spring constant of 260 N/mN/m and compresses it by 65 cm. What was the speed of the cart just before it hit the spring?

A toy car of mass 2.0 kg starts at the top of an incline of angle 20.°. It travels 1.0 meter down the incline to a flat surface where it encounters a spring of spring constant, k = 5.0 N/m. (a) What is the car's speed at the bottom of the incline? (b) When the car encounters the spring, by how much does it compress (max) it? (c) The spring is removed and the car now encounters a second incline as shown. What is the maximum distance the car travels up this second incline?

A 20 kg box is released from rest on a friction incline of 40 degrees from the horizontal. 5 m down the incline there is a spring of spring constant 1500 N/m. How much does the box compress the spring before coming to rest?

A spring with spring constant of 100 N/m launches a 20 g ball verticallyn into the air. If the ball reaches a height of 20 m, determine the original compression distance of the spring.
