The particle executing simple harmonic motion has a kinetic energy K0 cos^2 ωt. The maximum values of the potential energy and the total energy are respectively ___________
(a) Kc/2 and K0
(b) K0 and K0
(c) K0 and 2K0
(d) 0 and 2K0
(a) Kc/2 and K0
(b) K0 and K0
(c) K0 and 2K0
(d) 0 and 2K0
The correct option is (b) K0 and K0
For explanation: When kinetic energy is maximum, potential energy is zero and vice-versa. But
Kinetic energy+ Potential energy = Total energy
Maximum potential energy = Maximum kinetic energy = Total energy = K0.
