Question

A spring bounces up and down 15 times in 25 seconds. What is the period of a single bounce?

Answer 1

Answer:

1 2/3 seconds

Explanation:

instead of period, lets use "the amount of time it takes for the spring to bounce once." 25/15=5/3=1 2/3.

Answer 2

Answer:

Period = 1.67secs

Explanation:

Period t = time/ number of circle

Therefore t = 25/15

= 1.67secs
