The values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35
The function is given as:
h = 156t - 16t^2
When the height is 60 feet, we have:
156t - 16t^2 = 60
Rewrite as:
16t^2 - 156t + 60 = 0
Divide through the equation by 4
4t^2 - 39t + 15 = 0
Next, we solve the equation using a graphing calculator
From the graphing calculator, we have:
t = 0.40 and t = 9.35
Hence, the values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35
