A 6.30 kg block is pushed 9.45 m up a smooth 40 degree inclined plane by a horizontal force of 70 degrees north. If the inital speed of the block is 3.20 m/s up the plane:
(a) Calculate the kinetic energy of the block.
(b) Calculate the work done by the 70 N force.
(c) Calculate the work done by gravity.
(d) Calculate the work done by the normal foce.
(e) Calculate the final kinetic energy of the block.
