A 250 kg hammer of a drop force is released from a
height of 2.50 m above a 0.500 cm thick sheet of
aluminum. If the impact with the aluminum lasts 12.0
ms, determine: (a) the magnitude of the linear
momentum of the hammer just before impact. (b) The
force exerted on the aluminum by the hammer. (c) The
diameter of a circular hole that this force could punch in
the aluminum
