Problem
A high jumper lands on a thick foam mat instead of the hard ground. Compared to landing on the hard ground, the average force exerted on the jumper by the mat is
(a) Greater because the contact time is shorter
(b) Smaller because the contact time is longer
(c) Smaller because the impulse acting on the jumper is smaller
(d) The same because the mass of the jumper is unchanged
