Consider hitting a baseball with a bat. If we call the force on the bat against the ball the action force, identify the reaction force. Consider hitting a baseball with a bat. If we call the force on the bat against the ball the action force, identify the reaction force. The reaction force is zero because the force of the bat on the ball is equal and opposite to the force of the ball on the bat. The reaction force is the force by the ball on the bat. The reaction force is the force of the bat on the ball. The reaction force is the force due to compression inside the ball:

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
