A disk is turning with uniform circular motion a point on

A disk is turning with uniform circular motion. A point on the rim of the disk is moving with velocity v1 = (1.5 m/s)i + (2.0 m/s)j at t1 = 3.00 ms and v2 = (?1.5 m/s)i + (?2.0 m/s)j at t2 = 7.00 ms.

(a) What is the magnitude of the point's centripetal acceleration?

(b) What is the point's average acceleration during the time interval (t2- t1)?
