An object of mass 1.00kg is moving over a horizontal circular path of radius 2.00m, with a speed of 3.00ms^-1. Determine:
(a) its centripetal acceleration
(b) its kinetic energy
(c) its period
(d) its angular velocity
a: 3.00^2/2.00 = 4.5 ms^-1
b: 0.5 × 1.00 × 2.00^2 × 3.00/2.00^2 =0.5 × 1.00 × 4 × 2.25 = 4.5 J
c: 2 × pi × 2.00/3.00 = 2 × pi × 0.6 = 4/3pi = 4.19s
d: 3.00÷2.00= 1.5ω

on d, the units are radians/sec or 1/sec
Thank you so much!
