Question

A particle makes a smooth periodic motion on a path 20 cm long. When it is 6 cm away from the mean position, its velocity is 26 cm / s. So the value of acceleration when it is 3 cm away from the positive end?​

Answer 1

Answer:

2m/s2

10=20sin ωt

∴ωt=(π6)⇒t=π6ω

The desired time will be 2t

or π3ω=π3(2π/T)=T6=126=2m/s2
