An electric turntable 0.750 meter in diameter is rotating about a fixed axis with an initial angular velocity of 0.250 rev/s and a constant angular acceleration of 0.900 rev/s squared.
a. Find the angular velocity of the turntable after .200 sec.
b. Find through how many revolutions has the turntable spun in this time interval?
c. Calculate the tangential speed of a point on the rim of the turntable at t= 0.200 sec?
d. Find the magnitude of the resultant acceleration of a point on the rim at t= 0.200 sec?
