Question

multiple - choice question
to apply a negative impulse to the ball carrier, a defensive player will have to...
apply a force in the opposite direction the ball carrier is running.
apply a force in the same direction the ball carrier is running.

Explanation:

Impulse is defined as the change in momentum, and it is given by the formula $J = F\Delta t$. A negative impulse means a decrease in the momentum of the ball - carrier. According to Newton's second - law, force and impulse are related. To decrease the momentum (negative impulse), a force in the opposite direction of the motion of the ball - carrier is needed as it will act to slow down the ball - carrier.

Answer:

apply a force in the opposite direction the ball carrier is running.
