24. In the previous question, the object with mass m= 3.0 kg sits on the merry-go-round at a distance R= 2.0 m from the center, and is moving with constant angular velocity, with a period T = 1.57 sec. What is the magnitude of its acceleration ? (regular linear acceleration, not angular acceleration, and not just the tangential component of the acceleration: we are asking for the magnitude of the acceleration vector.)

Question

Please show how to solve for #24. The answer is A, but I don't understand how to get there. I have solved for a perpendicular using a = v^2/r and substituting with v = 2 pi r / T.  a perpendicular = 50.29 m/s^2, but I am not sure how to solve for a parallel using the equation (a parallel = r * angular acceleration.) Thanks!

T = period

r = radius

a = acceleration
