11. The turntable of a record player rotates initially at a rate of 33 rev/min and takes 20 s to come to rest (a) What is the angular acceleration of the turntable, assuming the acceleration is constant? (b) How many rotations does the turntable make before coming to rest? (c) If the radius of the turntable is 0.14 m, what is the initial linear speed of a bug riding on the rim? (d) What is the magnitude of the tangential acceleration of the bug at time t=0?
