- A car crashes into a large tree that does not move. The car goes from 30 m/s to 0 in 1.3 m. (a) What impulse is applied to the driver by the seatbelt, assuming he follows the same motion as the car? (b) What is the average force applied to the driver by the seatbelt?arrow_forwardA crate of mass M is initially at rest on a frictionless, level table. A small block of mass m (m M) moves toward the crate as shown in Figure P10.31. Later, the block and crate are stuck together and are moving with some final speed. The momentum of the blockcrate system is the same both before and after the collision. Is the magnitude of the change in momentum of the crate greater than, less than, or equal to the magnitude of the change in the momentum of the block? Explain. FIGURE P10.31arrow_forwardA 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/sarrow_forward

(b) Which has greater kinetic energy, the ball or the bullet?arrow_forwardTwo pucks in a laboratory are placed on an air table. Puck 1 has twice the mass of puck 2.
