The 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
Options
- A1.44 ~m
- B0.72 ~m
- C2.88 ~m
- D0.36 ~m
Correct answer
A. 1.44 ~m
Step-by-step solution
Velocity, v=r t0.4=r 2 16 2 16 2=r 2 16 1 2 or r= 0.4 16 2 2 = 3.2 2 =1.44 ~m
