Solve the following question given below:
Question: A cat rides a merry-go-round turning with uniform circular motion. At time t1 = 2.00 s, the cat's velocity is (3.00 m/s)i+(2.30m/s)j, measured on a horizontal xy coordinate system. At t2= 5.60s, its velocity is (-3.00m/s)i+(-2.30)j.
Part A: What is the magnitude of the cat's centripetal acceleration?
Part B: What is the magnitude of the cat's average acceleration during the time interval t2-t1, which is less than a period of the motion?
Please also explain, thank you in advance.
