In this problem we consider a mass moving in a circle of radius R with angular velocity an Review I Constants Part A F(t) = R cos(wt)i + sin(wt)} = R cos(wt)i + R sin(wt)j. What is the velocity of the mass at a time t? You can work this out geometrically with the help of the hints, or by differentiating the expression for T (t) given in the introduction. (Figure 2) The main point of the problem is to compute the acceleration using geometric arguments. (Figure 1) Express this velocity in terms of R, w, t, and the unit vectors i and j.
