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.
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
vf^2= 2ax
delta L= mg/k
_/(k/m) A- square rt of k/m times A
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!
