A particle is executing the motion x=Acos (ωt-θ). The maximum velocity of the particle is

Options

(a) Aω cosθ
(b) Aω
(c) Aω sinθ
(d) None of these

Correct Answer:

Aω

Explanation:

x = A cos (ωt – θ)

Velocity = dx/dt = -A sin (ωt – θ)

For maximum value, Since function should be = 1

Maximum velocity = -Aω
