Answer:
B) 36 ft
Step-by-step explanation:
Given:
The height as a function of time is given as:
At maximum height, the instantaneous velocity becomes 0. The instantaneous velocity is the first derivative of the height function.
So, the derivative of the the given function is 0 at the maximum height.
Differentiating the above function with time, we get
Now, equating the derivative to 0 and finding time.
Therefore, time taken to reach maximum height is 1.5 s.
Now, maximum height is obtained by plugging in in the height equation.
Maximum height is given as:
