The ball takes 1.5 seconds to reach its maximum height
The ball's maximum height is 44 feet
Solution:
Given that,
The height in feet after t seconds is given by the function:
Let us first find the derivative of h(t)
Differentiate the given function with respect to t
At the maximum height the derivative of the function needs to be 0
Thus the ball takes 1.5 seconds to reach its maximum height
Find the ball's maximum height:Substitute t = 1.5 in given function
Thus ball's maximum height is 44 feet
