Answer:

Part 1) Option A. h(2) = 86.00 means that after 2 seconds, the height of the ball is 86.00 ft

Explanation:

we have


h(t)=-16t^(2)+150

where

t ----> is the time in seconds after the ball is dropped

h(t) ----> he height in feet of a ball dropped from a 150 ft

Find h(2)

That means ----> Is the height of the ball 2 seconds after the ball is dropped

Substitute the value of t=2 sec in the equation


h(2)=-16(2)^(2)+150=86\ ft

therefore

After 2 seconds, the height of the ball is 86.00 ft.
