a) Find the impulse (magnitude and direction) experienced by the football during the collision.

b) Find the impulse (magnitude and direction) experienced by the child during the collision.

c) Suppose the collision lasted 0.254 sec. Find the average force (magnitude and direction) experienced by the child during the collision.

d) What was the child’s average acceleration during the collision?

e) Characterize the collision as elastic, inelastic, or completely inelastic

**bobpursley**, Tuesday, July 16, 2013 at 4:52pmWhat is your question about this? It appears straightforward.

a. impulse = change momentum

initial momentumball=finalmomentumball+finalmomentum child

.75*21.1=(.75+48)velocityfinal

solve for velocity fnal, then determine the momentum change of hte ball, and the child.

c. force*time=changemomentum
