Questions
In the given figure, represents the total acceleration of a particle moving in the clockwise direction in a circle of radius R = 2.5 m at a given instant of time. The speed of the particle is
detailed solution
Correct option is A
Here, a=15 m s-2R = 2.5mFrom fig,ac=acos30°=15×32 m s-2 As we know, ac=v2R⇒v=acR∴v=15×32×2.5=5.69≃5.7 m s-1Talk to our academic expert!
