A Hooke's law spring is compressed a distance d and is used to launch a mass m vertically to a height h above its starting position.Under double the compression,the spring is now used to launch the mass.How high does the mass now rise above its starting position?
A) 2 h
B) 1.41 h
C) 3 h
D) 4 h

Question

Quizplus · Accepted Answer

Doubling the compression of the spring quadruples the potential energy stored in the spring (since potential energy is proportional to the square of the compression distance). Therefore, the mass will rise to four times the original height, h.
