Question

The displacement of a particle in shm is indicated by equation y= 10sin(20t+π/3) where y is in meters. The value of maximum velocity of the particle will be

(1) 100m/s
(2) 150m/s
(3) 200m/s
(4) 400m/s

Answer 1

Here A=10 and  ω=20

Vmax=?

We know that,

Vmax=Aω

        =10*20

        =200m/sec

Answer 2

the answer of this Question is 100pie m/s
