Question

A point particle of mass 0.1 kg is executing S.H.M. of
amplitude of 0.1 m. When the particle passes through the
mean position, its kinetic energy is 8 × 10⁻³ Joule. Obtain

oscillation is 45º.
(a) y 0.1sin (±4t + π/4)
(b) y 0.2sin (±4t + π/4)
(c) y 0.1sin (±2t + π/4)
(d) y 0.2sin (±2t + π/4)
