suppose that a horizontal force of 0.7 n is required to pull a 5.0 kg block across the table at constant speed. what is the initial speed of a 20 g bullet, fired horizontally into the block, if the bullet imbeds in the initially stationary block and causes the block to slide 1.50 m across the table before coming to rest again??

    Use the numbers in the first statement to compute the coefficient of kinetic friction.

    In the second part, set the momentum of the bullet equal to the impulse given in the opposite dorection by friction.
