A 4.4 kg block is pushed 6.6 m up a rough 35° inclined plane by a horizontal force of 74 N. If the initial speed of the block is 2.2 m/s up the plane and a constant kinetic friction force of 25 N opposes the motion, calculate the following.
(a) the initial kinetic energy of the block J
(b) the work done by the horizontal force J
(c) the work done by the friction force J
(d) the work done by gravity J
(e) the work done by the normal force J
(f) the final kinetic energy of the block J
