The maximum velocity of a point undergoing simultaneous two oscillations given by `x_(1) =a cos wt` and `x_(2) = a cos 2 wt`is:

A

`2.74 aw`

B

`2aw`

C

`1.414aw`

D

`aw`

Text Solution

Verified by Experts

The correct Answer is:
A
`x = a cos wt +a cos 2 wt`
`v = (dx)/(dt)` For `v_(max), (dv)/(dt) = 0`
`rArr cos wt = 0.64 :. V_(max) = 2.74 aw`
