Acat rides a merry-go-round while turning with uniform circular motion. at time t1 = 2.00 s, the cat's velocity is v with arrow1 = (2.30)i hat + (4.00 m/s)j, measured on a horizontal xy coordinate system. at time t2 = 9.00 s, a half-revolution later, its velocity is v with arrow2 = (-2.30 m/s)i hat + (-4.00 m/s)j.

Part a)

Part b)

Explanation:

As we know that it makes half revolution in given time interval

so we have

now the angular speed is given as

now linear speed is given as

now we have

Now centripetal acceleration is given as

Part b)

Average acceleration of the cat is given as
