Explanation:
Answer:
117.88m
Explanation:
We can use the formula [ s = ut + 1/2at^2 ] to solve this problem.
We know that constant acceleration is a = 9/8m/a^2, the initial velocity is 0, and the height is 87 so the only variable we need to solve for is "t".
87 = 0t + 1/2(9.8)(t^2)
t = √174/9.8
t = 4.21s
Now multiply the time by the speed given.
28m/s * 4.21s = 117.88m
Best of Luck!
