Question

An electric turntable 0.750 m in diameter is rotating about a fixed axis with an initial angular speed of 0.250 rev/s and a constant angular acceleration of 0.900 rev/s2.

(a) Compute the angular velocity (in rad/s) of the turntable after 0.200 s.

(b) Through how many revolutions have the turntable spun during this time interval?

(c) What is the tangential speed of a point on the rim of the turntable at t = 0.200 s? (d) A 0.850-g bug is located on the rim of the turntable. What is the magnitude of the resultant force on the bug at t = 0.200 s?
