A spring with a spring constant of 5000 N/m is compressed 25 cm by a mass of 2 kg. The mass is released and the spring propels the mass across the floor. After the mass leaves the spring it experiences drag on the floor. The kinetic coefficient of friction between the mass and the floor 0.25.

A block of mass 0.25 kg is against a spring compressed at 0.20 m with spring constant 50 N/m. When the spring is released, the block moves along the frictionless surface until entering a region with the coefficient of kinetic friction equal to 0.30 (when the block enters the friction region it is no longer in contact with the spring ). How far,L,into the region with friction does the block slide before stopping?

A vertical elastic spring with a spring constant of 619 N/m is compressed 25 cm. A ball of mass 320 grams is placed at rest on top of the compressed spring. Take that the height of the ball at this position is zero. The spring is then released so the ball is shot straight up. a)Find the total initial energy of the system consisting of the ball and the spring. b)Find the total potential (i.e before the ball is shot)...

A horizontal spring with spring constant 150 N/m is compressed 17 cm and used to launch a 2.9 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 spring with a spring constant of 302 N/m is initially compressed by a distance of 0.078 m from its equilibrium position. A mass of 0.038 kg is then held against the compressed spring and released from rest while upon a horizontal, frictionless surface. Assuming that the spring then pushes the mass across the surface, with speed does the mass leave the spring? Assume proper SI Units.
