Question

If a ball is thrown upward at 64 feet per second from a height of 8 feet, the height of the ball can be modeled by S=8+64t-1612 feet, where t is the

number of seconds after the ball is thrown. How long after the ball is thrown is the height 36 feet?
It takes seconds for the ball to reach the height 36feet.
(Type an integer or a simplified fraction. Use a comma to separate answers as needed.)

Answer 1

It takes approximately 2.5625 seconds for the ball to reach a height of 36 feet.

Step-by-step explanation:

To find out how long after the ball is thrown is the height 36 feet, we need to solve the equation when S = 36.

8 + 64t - 1612 = 36

64t = 164

t = 164/64 = 2.5625

Therefore, it takes approximately 2.5625 seconds for the ball to reach a height of 36 feet.
