In the given figure, `a=15m//s^(2)` represents the total acceleration of a particle moving in the clockwise dirction in a circle of radius `R=2.5`m at a given instant of time. The speed of the particle is

A

5.7 m/s

B

6.2 m/s

C

4.5 m/s

D

5.0 m/s

Text Solution

Verified by Experts

The correct Answer is:
A
`a_(c ) = v^(2)/r`
`15 cos 30^(@) v^(2)/2,5`
`v^(2) = 32.44`
`v = 5.7` m/sec
