Question

A construction worker dropped a hammer while building the Grand Canyon skywalk, 4000 feet above the Colorado River. Use the formula, t = h 4 , to find how many seconds it took for the hammer to reach the river. Round your answer to the nearest second.

Answer 1

Answer: Hammer reaches river after 15.8 seconds.

Step-by-step explanation:

Use formula: t = square root of h divided by 4. In this problem h = 4,000.

Therefore,

T = square root of 4,000 divided by 4.

T = 15.8 seconds
