A 3.00 kg mass is pushed against a spring and released. If the spring constant of the spring is 7500 N/m and the spring is compressed 10.0 cm. (a) What is the energy stored in the compressed spring? (b) What is the maximum speed ?0 of the mass? (c) The mass then travels across a rough surface and then up a smooth ramp. The speed at the beginning of the ramp is ?1 = 4.00 m/s. What is the work done by friction as the mass moves across the rough surface? (d) The block then travels up the smooth ramp and continues on vertically. How high does it go?

A block of mass 0.630 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m. When it is released, the block travels along a frictionless, horizontal surface to point circled A, the bottom of a vertical circular track of radius R = 1.00 m, and continues to move up the track. The speed of the block at the bottom of the track is...

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?
