A 50 kg crate slides down a ramp that is inclined by 30 degrees from the horizontal. The acceleration of the crate parallel to the surface of the ramp is 2.0m/s^2, and the length of the ramp is 10m. Determine the kinetic energy accumulated by the crate when it reaches the bottom of the ramp if it started from rest at the top of the incline. Calculate the amount of energy lost by the crate due to friction in its...

A 1.50-kg block is on a frictionless, 30 degrees inclined plane. The block is attached to a spring (k = 40.0N/m ) that is fixed to a wall at the bottom of the incline. A light string attached to the block runs over a frictionless pulley to a 60.0-g suspended mass. The suspended mass is given an initial downward speed of 1.40m/s. How far does it drop before coming to rest? (Assume the spring is unlimited in how far it...
