A 6.30 kg block is pushed 9.00 m up a smooth 36.0° inclined plane by a horizontal force of 74.0 N . If the initial speed of the block is 3.15 m/s up the plane. Required:
a. Calculate the initial kinetic energy of the block.
b. Calculate the work done by the 80.0N force.
c. Calculate the work done by gravity.
d. Calculate the work done by the normal force.
e. Calculate the final kinetic energy of the block.
