A65 kg person jumps from a window to a fire net 18 m below, which stretches the net 1.1 m. assume the net behaves as a simple spring and
a) calculate how much it would stretch if the same person was lying on it.
b) how much it would stretch if the person jumped from 35 m

0.03167 m

1.52 m

Explanation:

x = Compression of net

h = Height of jump

g = Acceleration due to gravity = 9.81 m/s²

The potential energy and the kinetic energy of the system is conserved

The spring constant of the net is 20130.76 N

From Hooke's Law

The net would strech 0.03167 m

If h = 35 m

From energy conservation

Solving the above equation we get

The compression of the net is 1.52 m
