A 45 kg cart is pushed up a ramp a length of 5.8 m from rest, attaining a speed of 2.6 m/s
at the top of the ramp, which is 1.7 m high. The coefficient of friction between the cart
and the ramp is 0.13.
a) Determine the work done against:
1) gravity 2) inertia 3) friction.
b) What force was used to push the cart?
c) What power was used to move the cart?
