Question

This time period of a particle undergoing SHM is 16 s . It starts motion from the mean position. After 2 s , its velocity is 0.4 m s - 1 . The amplitude is, 1 . 44 m, 0 . 72 m, 2.88 m, 0.36 m

MARKS App · Accepted Answer

Velocity, v = r ω cos ⁡ ω t ; 0.4 = r × 2 π 16 cos ⁡ 2 π 16 × 2 = r × 2 π 16 × 1 2 or r = 0.4 × 16 × 2 2 π = 3.2 2 π = 1.44 m
