When a 58g tennis ball is served, it accelerates from rest to a constant speed of 36 m/s. the impact with the racket gives the ball a constant acceleration over a distance of 35 cm. what is the magnitude of the net force acting on the ball?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
