Question

How long would it take for a ball dropped from the top of a 576576-foot building to hit the ground? Round your answer to two decimal places.

Answer 1

Answer:

5.98 s

Step-by-step explanation:

576 ft = 576 / 3.28 = 175.56 m

Let g = 9.81 m/s2. The time it takes for the ball to fall from 165.56 m high to the ground is

$s = gt^2/2$

$t^2 = 2s/g = 2*175.56/9.81 = 35.8$

$t = \sqrt{35.8} = 5.98 s$
