QUESTION: A 200 N/m, 5 m spring on a 20 degree incline is compressed 2.3 m and a 5 kg block is placed on it. If we neglect friction, how far up the incline will the block travel? How fast will it be traveling when it is 0.2 m up the incline? EQUATION: 1/2kx^2 + mgh + 1/2mv^2...

Physics please help!!
A 1.94 kg solid sphere (radius = 0.105 m) is released from rest at the top of a ramp and allowed to roll without slipping. The ramp is 0.710 m high and 5.17 m long. When the sphere reaches the bottom of the ramp, what is its total kinetic energy?

need help with this question please a 1kg block starts at rest and slides down the incline. the coefficient of friction between the incline and the block is 0.1. The height of the incline is 2m, and the angle is 30 degrees. use energy consideration to find the block's speed at...
