The speed of a bullet can be measured by firing it at a wooden cart initially at rear and measuring the speed of the cart with the bullet embedded in it. Figure P4.80 shows a 12-g bullet fired at a 4.0-kh cart. After the collision, the cart rolls at 1.8 m/s. What is the bullet's speed before it strikes the cart?
