a 90.0 kg skydiver hanging from a parachute bounces up and down with a period of 1.50 seconds. What is the new period of oscillation when a second skydiver, whose mass is 60.0 kg, hangs from the legs first?

the answer is 1.94 seconds

## Homework Equations

I think it has something to do with the the simple harmonic oscillator:

T = 2 (pi) sqrt(m/k)

I also tried the simple harmonic equation involving sin:

y=sinAwt=Asin sqrt(k/m)t

but i keep on getting 0.129 seconds.

I attempted this several times and is stuck on how to do it. I am studying for exams and there are several questions similar to it. Can someone help me please! :)
