Atennis ball with a speed of 25.9 m/s is moving perpendicular to a wall. after striking the wall,
the ball rebounds in the opposite direction with a speed of 21.3157 m/s. if the ball is in contact
with the wall for 0.0133 s, what is the average acceleration of the ball while it is in contact with
the wall? take "toward the wall” to be the positive direction. answer in units of m/s 2

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:

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
