During a ballistics test, a bullet of mass 1.37 g is fired through a block of mass 5.4 kg. in this particular test, the block is traveling horizontally towards the bullet. the bullet takes only 0.023 seconds to pass through the block as it reverses the block's velocity from 1.59 m/s to the right to 0.6 m/s to the left with constant acceleration. find the magnitude of the force that the bullet exerts on the block during the test.____
