A 70.0 kg man jumping from a window lands in an elevated
Chapter , Problem 112(choose chapter or problem)
A 70.0 kg man jumping from a window lands in an elevated fire rescue net 11.0 m below the window. He momentarily stops when he has stretched the net by 1.50 m. Assuming that mechanical energy is conserved during this process and that the net functions like an ideal spring, find the elastic potential energy of the net when it is stretched by 1.50 m.

QUESTION:
A 70.0 kg man jumping from a window lands in an elevated fire rescue net 11.0 m below the window. He momentarily stops when he has stretched the net by 1.50 m. Assuming that mechanical energy is conserved during this process and that the net functions like an ideal spring, find the elastic potential energy of the net when it is stretched by 1.50 m.
ANSWER:Step 1 of 2The elastic potential energy of the net is equal to the change in potential energy of the personfalling from the window till he stopped.
