The height, h, of an object that is thrown upwards into the air can be represented as h = 0.5at2 + v0t + h0, where a represents the acceleration due to gravity (– 32 ft/s) 2), v0 represents the initial velocity, in feet per second, h0 represents the initial height of the object, in feet, and t represents time, in seconds.

Part A:
A ball thrown upwards from the top of a 64–ft high building with an initial velocity of 48
ft/s. Write an equation that could be used to determine the time, t, in seconds, for the ball to reach the ground. Assume ground level is at a height of 0 ft.

Part B:
Determine the time, t, in seconds, that takes the ball to reach the ground and explain how you determined your answer.
