A spring with force constant of 58 N/m is compressed by 3 cm in a hockey game machine. The compressed spring is used to accelerate a small metal "puck" with mass 27.8 grams which will then slide up an inclined surface inside the machine. Assume friction is so tiny it may be ignored in this problem. How high in cm above its initial vertical position will the puck rise before stopping (momentarily at least)? Note: Convert units as necessary.

A spring with spring constant 28 N/m is compressed a distance of 7.5 cm by a ball with a mass of 201.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 7.5 cm and is also released, leaving the spring at point A....

A horizontal spring with spring constant 130 N/m is compressed 19 cm and used to launch a 2.8 kg box across a frictionless, horizontal surface. After the box travels some distance, the surface becomes rough. The coefficient of kinetic friction of the box on the surface is 0.15. Use work and energy to find how far the box slides across the rough surface before stopping. Express your answer to two significant figures and include the appropriate units.

A light spring of force constant 3.90 N/m is compressed by 8.00 cm and held between a 0.250 kg block on the left and a 0.520 kg block on the right. Both blocks are at rest on a horizontal surface. The blocks are released simultaneously so that the spring tends to push them apart. Find the maximum velocity each block attains if the coefficient of kinetic friction between each block and the surface is the following. In each case, assume...

The ball launcher in a pinball machine has a spring that has a force constant of 1.20 N/cm (Fig. P7.63). The surface on which the ball moves is inclined 10.0 degree with respect to the horizontal. If the spring is initially compressed 4.50 cm, find the launching speed of a 90 g ball when the plunger is released. Friction and the mass of the plunger are negligible.
