## Homework Statement

An electric turntable 0.760m in diameter is rotating about a fixed axis with an initial angular velocity of 0.250rev/s . The angular acceleration is 0.900rev/s2 .

what is the magnitude of the resultant acceleration of point on the tip of the blade at time 0.200

## Homework Equations

none given

the angular velocity at time 0.200 is 0.43

the tangential speed at time 0.200 is 1.03 m/s

## The Attempt at a Solution

I have tried doing sqrt(tangential acceleration^2 + radial acceleration^2)

my answer attempts are
