An 7 g bullet is shot into a 4.7 kg block, at rest on a frictionless horizontal surface. The bullet
remains lodged in the block. The block moves into a spring and compresses it by 3.4 cm. The
force constant of the spring is 1994 N/m. In the figure, what is the impulse on the block
(with the bullet embedded in it), due to the spring, during the entire time interval in which the spring brings
the block to a rest? Consider the positive direction to be to the right.
