## Homework Statement

A flywheel turns through 40 rev as it slows from an angular speed of 1.5 rad/s to a stop.Assuming a constant acceleration,find the tme for it to come to rest.

## Homework Equations

##w-w_0=∝t##

## The Attempt at a Solution

In Δt secon the change in w will be 1.5 and this time it will rotate 40 times..I tried every equaiton like

0-1.5=∝t

or

40=1.5t-1/2∝t^2

but I couldnt found
