Question

Quizplus · Accepted Answer

The direction of the impulse on a struck baseball is in the direction of the ball's change in velocity, which is represented by Newton's second law of motion, F=ma. The force applied to a baseball causes it to accelerate and change direction, resulting in a change in velocity. The impulse experienced by the baseball is in the same direction as this change in velocity.
