A car with 58-cm-diameter tires accelerates uniformly from rest to 20 m/s in 10 s. How many times does each tire rotate?
A computer hard disk 8.0 cm in diameter is initially at rest. A small dot is painted on the edge of the disk. The disk accelerates at 700 rad/s^2 for 1/2s, then coasts at a steady angular velocity for another 1/2s. What is the speed of the dot at t= 1.0 s? Through how many revolutions has it turned?
A drill, at its highest speed, rotates at 6500 rpm. If the drill takes 0.590 s to go from rest to full speed, how many revolutions does it make in that time? 1.92×103 rev 32.1 rev 202 rev 402 rev
