Atennis ball with a speed of 27.7 m/s is moving perpendicular to a wall. after striking the wall, the ball rebounds in the opposite direction with a speed of 19.7224 m/s. if the ball is in contact with the wall for 0.0146 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 .

a = 3248 m/s^2

Explanation:

Given:

vi = 27.7 m/s

vf = -19.7224 m/s ***note the negative direction

t = 0.0146

a = ?

acceleration = change in speed / change in time

a = (27.7 - [-19.7224]) / 0.0146

a = 47.4224 / 0.0146

a = 3248 m/s^2

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
