Homework Help: Angular velocity

  1. Oct 31, 2005 #1
    The angular position of a point on the rim of a rotating wheel is given by theta = 4* t - 3* t^2 + t^3, where theta is in radians if t is given in seconds.

    find the angular velocities as t = 1 and t = 5.5

    i plugged the numbers into the given equation to get 2 and 97.625
    then i divided by the time to get 2 and 17.75 but both of these are wrong. what am i forgetting?

    You are given a position equation, and you want to find the velocities at certain points in time.. do you know the relationship between position equations and velocity equations? Think calculus
