What is the kinetic energy at the bottom?

What would be the kinetic energy in the absence of friction?

What happened to the difference?

Is there any other way to solve this problem beside KE? I haven't learn that yet. Thanks

Sum of forces along the ramp = ma

One force is gravity.

Second force is friction.

(Third force is force pushing up against the car. Why is this irrelevant?)

Get a from ramp length s and final velocity v.

Hint: dv/ds = dv/dt dt/ds = a/v.
