A truck with 0.100 m radius tires travels at 24.0 m/s. At how many radians per second are the tires rotating? What is this in rpm?

Physics 
Henry,
Circumference = pi * 2r =
3.14 * 0.20 = 0.6283 m/rev.
Va = 24m/s * 6.28rad/0.6283m = 240 rad/s
= Angular velocity.
V = 24m/s * 1rev/0.6283m * 60s/min =
2292 RPM.
