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
A billiard player sends the cue ball toward a group of three balls that are initially at rest and in contact with one another. After the cue ball strikes the group, the four balls scatter, each traveling in a different direction with different speeds as shown in Figure P10.30. If each ball has the same mass, 0.16 kg, determine the total momentum of the system consisting of the four balls immediately after the collision. FIGURE P10.30
