Question

A particle is performing simple harmonic motion. At time ‘t’, its displacement from the mean position is x and its speed is v. The corresponding resultant force on it is F and its acceleration is a. At the same time, it has kinetic energy K and potential energy U.

The variation of kinetic energy (k) with displacement (x) is given by the graph

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

$K=\frac{1}{2}m{\omega }^2(A^2-x^2)$
