Question

you decide to install a rope swing at the bend in the river. the time t in seconds for the rope swing to make one swing is given by 2√l/3.3, where l is the length of the rope swing in feet. If one swing takes 3.5 seconds, how long is the rope swing? Round your answer to the nearest tenth foot.

Answer 1

t = 2√(l/3.3)

 

So, plug in t = 3.5 and solve for l.
