Linear Momentum & Collision
A lion of mass 120 kg leaps at a hunter with a horizontal velocity of 12 m/s. The
hunter has an automatic rifle firing bullets of mass 15 g with a muzzle speed of
630 m/s and he attempts to stop the lion in midair. How many bullets would the
hunter have to fire into the lion to stop its horizontal motion? Assume the bullets
stick inside the lion
