A spring with a spring constant of 718 N/m lies on a horizontal surface and that surface is y = 0 m to calculate the gravitational potential energy. A mass of 3 kg is compressed 0.45 meters into the spring and held still. After the mass is released it slides over a horizontal surface in which a 3.4 meter portion of the surface has friction with a coefficient of kinetic friction of 0.30. After the horizontal surface, it travels up a frictionless quarter-circular ramp and stops at the top of the ramp. What is the radius of the quarter-circular ramp in meters?

    A mass of 9 kg is placed on a horizontal frictionless surface and attached to a spring. The mass is compressed 0.69 meters on the spring from equilibrium and held still. It is then released and it travels across the horizontal surface, around a frictionless quarter circular ramp, and it is launched into the air vertically and reaches a maximum height of 6 meters above the ground. The same mass is then attached to the same spring and hung vertically...

    A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released from rest. It travels over a horizontal surface, up an incline which has a height (not length) of 5 meters, and then travels over another horizontal surface. At the end of that surface is another spring with the same spring constant. The mass hits the second spring and eventually stops after compressing it 2.3 meters. What is the elastic potential energy of the second...

    A block of mass 3 kg is pushed against a spring of spring constant 3000 N/m. Initially, the spring is compressed by a distance of 0.220 m, when the block is released from rest and travels along a horizontal frictionless surface before encountering a frictionless ramp, inclined at an angle of 37° above the horizontal. How far along the ramp does the block travel before momentarily coming to rest?
