Darryl throws a basketball at the gym floor. the ball bounces once on the floor and comes to rest in his coach’s hands. at which point are all the forces on the basketball balanced?

When ball comes to rest in coach's hand

Explanation:

As we know that net force on an object is given by

so here object will have some external unbalanced force if it is accelerated or we can say if object has changing velocity then it will have some external force on it.

Now when basketball bounces on the floor then at each moment the speed of the ball is changing due to force of gravity.

but as soon as the ball comes to the hand of coach then the speed of the ball comes to zero and not changing so at that point the net force on the ball must be balanced of zero

no image, but probably absorption

c) up is the direction the magnetic force is acting on the charge.
