A dragster is speeding down the track at 150m/s. its rear wheels are 2m in diameter, and its front wheels are 40cm in diameter. What are the angular velocities of the front and rear wheels, respectively?

Answer 1

150m/sec=2PI*radius/time
time for one rev = 2PI*radius/150

then w=2pi/timeabove=2PI*150/(2PI*radius)
= 150/radiusInMeters

check my thinking.
