Matthew pushes a box of toys along a 5 m long ramp that is inclined 3 m high as shown in the figure below. The box has a total mass of 20 kg and the coefficient friction between the box and the ramp is 0.33.    (a) How much force is needed by Matthew to move the box uniformly along the inclined ramp? (b) How much work is done by the force the box has travelled the 5.0 m length incline?  (c) How much work is done by friction? (d) How much work is done by gravity? (e) How much work is done by the normal force? (f) What is the total work done by all the forces on the box?

A worker pushes horizontally on a large crate with a force of 190 N, and the crate is moved 4.0 m. How much work was done? X J

The figure below shows an object with a mass of m = 7.60 kgthat starts from rest at point A and slides on a track with negligible friction. Point A is at a height of ha = 6.30 m. What is the net work (in J) done by the gravitational force on the object as it moves from point A to point C?

The figure below depicts a roller coaster track. The roller coaster car has a mass of 196 kg, and the heights of the two hills are h = 34.2 m and h2 = 14.8 m. At point A, the roller coaster car has a speed of 8.06 m/s. What is the car's kinetic energy (in Joules) at point C? Friction and air resistance can be neglected. A hy Roller Coaster

A 20 kg toddler tries hard to lift his mom’s 12 kg KSU book bag, applying a force of 25 N. The bag is heavy and he can’t begin to lift it. How much work does the helpful little guy do on the bag?
