    Centripetal Motion Problems: Solving for Velocity and Acceleration

    Homework Statement A centripetal-acceleration addict rides in uniform circular motion with period T = 4 s and radius r = 3.00 m. At one instant his acceleration is a = (7.00 m/s2)i + (-3.00 m/s2)j . At that instant, what are the following values? (a) v·a (b) r x a Homework Equations 2∏r/T...
