Question

a car moves on a circular path of radius 30m with a velocity of 2.5ms if it mass is 20g find its angular speed

Answer 1

r = 30m

v = 2.5 m/s

m = .02kg

_________________

v = r*omega

omega = (delta thaeda)/(delta time)

_________________

2.5 m/s = 30m*omega

.08333...  = omega

_________________

*note, omega stands for angular velocity

Also, it's been a while since I've done a physics problem like this so I could be wrong. I think this is the answer though :)
