Answer:
Explanation:
To find how long it took the ball to reach the end we use the formula
[tex]t= \frac{d}{v} \\ [/tex]
where
t is the time
d is the distance
v is the velocity
From the question
d = 18 m
v = 7.5 m/s
We have
[tex]t = \frac{18}{7.5} \\ [/tex]
We have the final answer as
Hope this helps you
