Based on Newton’s third law of motion, will a tennis ball go farther if it hits a tennis racquet that is still or one that is in motion?
One that is still because it will absorb all of the force of the ball.
One that is still because that will have a greater impact on the trajectory.
One that is in motion because both the ball and the racquet will contribute momentum.
One that is in motion because the racquet’s force will cancel the ball’s force out.
