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
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
