Erica throws a tennis ball against a wall, and it bounces back. which force is responsible for sending the ball back to erica?

The normal force that the wall exerts on the ball.

Explanation:

Erica throws a tennis ball against a wall, and it bounces back. Here Newton's third law of motion follows. When the ball hits the wall, the wall will also exert an equal and opposite force on the ball as per third law. The opposite force that wall exert on ball is normal force which is responsible for sending the ball back to Erica.

Hence, the force is normal force exerted by the wall on the ball.

are there answer choices to this question? this seems like a question where you have options to choose from.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
