A 5kg block initially at rest is pulled to the ight along a horizontal surface by a constant, force of 30N acting at 53 degrees above the horizontal. The coeffcient of kinetic friction is 0.2. The acceleration of gravity is 10 m/s^2
a) Find the speed of the block after it has moved 3.0m (I know this answer it is v=3.23 m/s)
b) Find the net work done on the block.
