Question

A block slides down a frictionless ramp from starting height of 15.0 meters, how fast is it going at the bottom of the ramp in m/s?​

Answer 1

Answer:

Hope it helps

Explanation:

Create another work-energy equation for the gravitational potential energy, kinetic energy, and work done by friction for the way down the ramp.The expression for the kinetic energy at the bottom of the ramp contains the final speed of the block. You should find the speed at the bottom of the ramp to be9.44 m/s
