A car is equipped with a bumper that is designed to absorb collisions. The bumper is mounted to the car using pieces of flexible tubing. The car is traveling at 1.5 m/s when it collides with a rigid black wall. If the wall exerts an average force of 44.1 kN on the car as the bumper is deformed a distance of 38.3 mm, how much work is being done on the car by the wall?

  • physics -

    The work is the force time the distance over which the force is exerted

    = 44.1kN * 38.3 mm
    =44,100 N * 0.0383 m
