This problem has three parts.
I enclose a pdf file with the three body diagrams requested.
Here is an explanation of them.
Part A: Make a
free-body diagram of this ball just before it hits the wall.
The only force acting on the ball is the pull of the Earth, this is its weight; so the diagram is a vertical vector downwards.
<span>
Part B: Make a free-body diagram of this ball just after it has bounced free of
the wall.
</span>
<span>Again, the only force acting on the ball is the pull of the Earth, its weight, and the free-body diagram is identical to that of the part A.
</span>
<span>
Part C: Make a free-body diagram of this ball while it is in contact with the
wall.</span>
When the ball is in contact with the wall, two forces act over it: the reaction of the wall, which is represented as a horizontal vector toward the left, and the gravity (weight), which is represented as a vertical vector downwards.
