car traveling at 28.8 m/s hits a stone wall . The driver, who is wearing a shoulder harness and seat belt, moves forward 0.93 m as the car stops. Assuming his acceleration is uniform, find his average velocity during the collision. in m/S

  • PHYSICS - ,

    average speed during constant acceleration = (end speed+start speed)/2
    = (0 + 28.8)/2 = -14.4 m/s

    Now if you want the average force for the next part of the qustion

    F = d momentum/ d time
    = - mass of driver (28.8) /(.93/-14.4)

  • PHYSICS - ,
