Rotational kinematic equations help

  1. Dec 14, 2006 #1
    A wheel 60.0 cm in diameter accelerates uniformly from 245 rpm to 395 rpm in 7.5 s. How far will a point on the edge of the wheel have traveled in this time?

    I keep getting 125.66, I dont really understand what forumal to use.

    Check out this thread from the last couple of days where the rotational kinematic equations were used by another student. Model your work after that poster's work. Show all the relevant equations, and then show your algebra and how you get to the answer.
