While playing basketball in PE class, Logan lost his balance after making a lay-up and colliding with the padded wall behind the basket. His 70-kg body decelerated from 10 m/s to 0 m/s in 0.20 seconds. a. Determine the force acting upon Logan's body.
b. If Logan had hit the concrete wall moving at the same speed, his momentum would have been reduced to zero in 0.0070 seconds. Determine what the force on his body would have been for such an abrupt collision
