a tennis player swings and hits the ball away. how does the force of the tennis racket of the tennis racket affect the motion of the ball?

it does not change the speed or the direction of the ball
or
it changes the speed of the ball but not the direction
or
it changes the direction of the ball but not speed
or
it changes both the direction and the speed of the ball

The correct answer is: it changes both the direction and the speed of the ball. The force applied by the tennis racket on the ball causes it to accelerate, changing its initial velocity (speed and direction).
