Agirl throws a tennis ball upward with an initial velocity of 4 m/s. what is the maximum displacement of the ball?

0.82 m

Explanation:

The ball is in free fall - uniform accelerated motion with constant acceleration downward, (acceleration of gravity). So we can use the following suvat equation to solve the problem:

where

v is the final velocity

u = 4 m/s is the initial velocity

a is the acceleration

s is the displacement

At the maximum displacement, v = 0 (the velocity becomes zero). Substituting and solving for s, we find:

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
