When a spring is compressed by 3 cm, the potential energy stored in it is U. When it is compressed further by 3 cm, the increase in potential energy is

View answer and explanation

Correct option: D

3 U

The correct answer is D. The potential energy stored in a spring is proportional to the square of the compression. Compressing it further by 3 cm results in a total compression of 6 cm, leading to a potential energy of 4U, so the increase is 3U.

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}
