7 Multiple Choice 1 point How does an impulse affect a running back who bounces off another player without stopping? It changes the player's direction It has no effect on the player It stops the player's momentum It increases the player's mass

The correct answer is: **It changes the player's direction.**<br /><br />Impulse is the change in momentum. Since momentum is a vector quantity (having both magnitude and direction), a change in direction represents a change in momentum, and therefore an impulse. The running back continues moving, so his momentum isn't stopped, and his mass remains constant.<br />
