Answer:
Explanation:
From this exercise, our knowable variables are <u>hight and initial velocity </u>
To find how much time does the <u>ball strike the ground</u>, we need to know that the final position of the ball is y=0ft
Solving for t using quadratic formula
or
<u><em>Since time can't be negative the answer is t=6.96s</em></u>
