time of impact on both the block and the expert's hand is the same force on both the block and the expert's hand have the same magnitude impulse on both the block and the expert's hand have the same magnitude all of these. none of these. ANSWER: D In any collision, there are always four quantities which are the same for both objects involved in the collision. Each object experiences the same force (Newton's third law) for the same amount of time, leading to the same impulse, and subsequently the same momentum change. Only the acceleration and the velocity change can differ for the two colliding objects. The lower mass object always receives the greater velocity change and acceleration.
