2. A cart with a mass of 100 kg is filled with 1,800 kg of coal. A force of 14 kN is used to pull the cart up a 23°incline that is 10.5 m long. The coefficient of kinetic friction between the cart and the incline is 0.300. Thecart is initially at rest at the bottom of the incline.(a) Find the work done by each of these forces: the force pulling the cart up the incline, gravity, friction,: and the normal force.(b) What is the net work done on the cart?(c) What is the cart's velocity at the top of the incline?

Work done by the force pulling the cart = F * d = 14 * 10^3 * 10.5 = 147000 J Work done by gravity =…

1. A 5kg block is push up a rough, inclined surface by a constant force of 20N. The surface is inclined at an angle of 15° and the force is applied completely horizontally and parallel to the ground below the incline. (Not parallel to the inclined surface). As a result, the velocity of the block increases from 0 m/s to 4 m/s in a displacement of 10m. A)What work was done by the frictional force during this displacement? B)What would have been the final velocity if friction was not present? C) Why was the final kinetic energy without friction higher than the total kinetic energy with friction?
