In an experiment designed to determine the velocity of a bullet fired by a certain gun, a wooden block of mass M = 500.0 g is supported only by its edges, and a bullet of mass m = 8.00 g is fired vertically upward into the block from close range below. After the bullet embeds itself in the block, the block and the bullet are measured to rise to a maximum height of 25.0 cm above the blocks original position. What is the speed of the bullet just before impact?
A football player of mass 95 kg is running at a speed of 5.0 m/s down the field as shown in Figure P11.53. A second player of mass 140 kg, running at a speed of 2.5 m/s, tackles the first player so that they move together after the collision. What is the velocity of the two players immediately after the collision? FIGURE P11.53 53. The football players have the same final velocity in this inelastic collision. We can use Equations 11.24 and 11.25 to determine the x and y components of the final velocity. The lighter player (95 kg) moves vertically, so v1ix = 0 and v1iy = 5.00 m/s. The other player (140 kg) moves to the right, so v2ix = 2.5 m/s and v2iy = 0. Therefore, m1v1ix+m2v2ix=(m1+m2)vfx(140kg)(2.5m/s)=(95kg+140kg)vfxvfx=1.5m/sm1v1iy+m2v2iy=(m1+m2)vfy Chapter 11 Collisions11.31 (95kg)(5.00m/s)=(95kg+140kg)vfyvfy=2.0m/s The final velocity is then vf=(1.5i+2.0j)m/s
