Question

A particle moves along a circular path of radius 3.0m with an angular velocity of 20rad/s.Calculate: [a] the linear velocity of the particle, [b] the angular velocity in revolutions per second, [c] the time for one revolution, [d] the centripetal force.

Answer 1

a)v =wr => v = 60
b)10/pi rev/s
c)pi/10 s
d)mv^2r....not sure about the formula its been quite a while since classical mechanics

Answer 2

d.(mv^2)/r=mrw^2
