35. A bicycle wheel with a radius of 0.42 m accelerates uniformly for 6.8 s from an initial angular velocity of 5.5 rad/s to a final angular velocity of 6.7 rad/s. What was its angular displacement during that time? What was its linear displacement? 36. An aluminum pie plate of radius 0.12 m spins and accelerates at a constant rate from 13 rad/s to 29 rad/s in 5.4 s. What was its angular acceleration? 37. An aluminum pie plate of radius 0.12 m is spins and accelerates at a constant rate from 13 rad/s to 29 rad/s in 5.4 s. What was its angular displacement during that time? 38. A record turntable rotating at 78.0 rpm is switched off and slows down uniformly to a stop in 30.0 s. What was its angular acceleration? How many revolutions did it make while slowing down? 39. A wheel starts from rest and accelerates with a constant a = 3.0 rad/s2. During a 4.0 s interval it rotates through an angular displacement of 120 radians. How long had the wheel been in motion at the start of that interval
