At time t1 = 2.00 s, the acceleration of aparticle in counterclockwise circular motion is (3.00 m/s2) i + (6.00 m/s2) j. It moves atconstant speed. At time t2 = 6.00 s (3/4 of a revolution later), itsacceleration is (6.00 m/s2)i + (-3.00 m/s2)j. What is the radius of the path taken by the particle?
