A robot arm moves so that B travels in a circle about Point A, which is not moving. Knowing that B starts from rest, and its
speed increases at a constant rate of 12 mm/s2, determine (a) the magnitude of the acceleration when t = 5 s, (b) the time for the magnitude of the acceleration to be 75 mm/s2
r=1.2m
