Erica throws a tennis ball against a wall, and it bounces back. which force is responsible for sending the ball back to erica? the force that the ball exerts on the wall the frictional force between the wall and the ball the acceleration of the ball as it approaches the wall the normal force that the wall exerts on the ball

actually the answer is D.

:)

explanation:

could i give you a exaplo that could you?

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
