A 1.00 x 10²-kg crate is being pushed across a horizontal floor by a force P that
makes an angle of 30° below the horizontal. The coefficient of kinetic friction is
0.200. (a) Draw the free-body diagram showing the forces that act on the crate.
(b) What should be the magnitude of P, so that the net work done by it and the
kinetic frictional force is zero?
