Question

A building is being knocked down with a wrecking ball, which is a big metal sphere that swings on a 15-m-long cable. You are (unwisely!) standing directly beneath the point from which the wrecking ball is hung when you notice that the ball has just been released and is swinging directly toward you. How much time do you have to move out of the way? answer in seconds.

Answer 1

Time to move out of the way = 1.74 s

Step-by-step explanation:

Time to move out of the way is one fourth of period = 6.95/4 = 1.74 seconds.
