1. The problem statement, all variables and given/known data 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 2. Relevant equations 2∏r/T = speed v^2/r = acceleration (4*∏^2*r)/T^2 = acceleration 3. The attempt at a solution a) (32.97m^2/s^3)i + (-14.13m^2/s^3)j b) (21m^2/s^2)i + (-9m^2/s^2)j Are these right?
