Answer:
Ball will not hit bell.
Explanation:
The height of the ball is modeled by the equation h(t)= -16t²+39t
We need to find if the bell is 25 ft above the ground, will it be hit by the ball.
So we need to find maximum height of the ball.
For maximum height we have
Substituting in h(t) = -16t²+39t
Maximum height reached = h(1.22) = -16 x 1.22²+39 x 1.22 = 23.77 ft
So maximum height reached is less than height of bell.
Ball will not hit bell.
