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
