The angular displacement of a flywheel v...

The angular displacement of a flywheel varies with time as `theta = at + bt^(2)-ct^(3)`. Then the angular acceleration is given by

A

`a+2bt-3ct^(2)`

B

`2b-6t`

C

`a+2b-6t`

D

`2b-6ct`

Text Solution

Verified by Experts

The correct Answer is:
D
`theta=at+bt^(2)+ct^(3)" "omega=(d theta)/(dt)=a+2bt-3ct^(2)`
`alpha=(d omega)/(dt)=2b-6ct`
