Question

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

Answer 1

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)

Answer 2
