Question

a particle along a circle of radius = 1 m so that its radius vector r relative to a point on its circumference rotates with constant angular velocity= 2 rads/s the linear speed of particle is?

pls solve fast urgent

Answer 1

R=0.50 m, 

ω=0.40 rad/s

θ=θ'/2

ω'=2ω

v'=2ωR=.40m/s

a=ω2R

a'=ω'2R=(2ω)2R=4ω2R=.32m/s2

Answer 2

V = Rω
V = 1×2
V = 2m/s
