Hi I'm having problems with solving this question:
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
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! :)
