The girl is going on a bungee jump. She weighs 65 kg. The rope is 11m. In total, she fell 36 m. The first 11 m is free fall, and another 25m is simple harmonic motion.(adsbygoogle = window.adsbygoogle || []).push({});

1) k of rope

2)max spped

3)what point when she has max speed

4)amplitude of rope

5)how long does it take

2. Relevant equations

vf^2= 2ax

delta L= mg/k

_/(k/m) A- square rt of k/m times A

3. The attempt at a solution

initial velocity = 0

acceleration= 9.8m/s^2

1) k of rope

i got k for 25.48

2)max spped

max speed for free fall= 14.7m/s

V_max for rope= 15.65m/s

So do I add them up or just 15.65??!

3)what point when she has max speed

36m?

4)amplitude of rope

25m?

Thanks!!!!
