Answer:

Explanation:
The initial velocity of the ball is
u = +25.9 m/s (towards the wall)
while the final velocity of the ball is
v = -21.3157 m/s (away from the wall)
The time taken for the change in velocity to occur is
t = 0.0133 s
The acceleration can be calculated as the change in velocity divided by the time taken:

Substituting the numbers, we find:

Gravity is all ways pulling down and the normal force acting on top of the object and for it to have to push or pull to the object
The meters per second
+1t a second / 2t
