Question

a particle of mass m moves in a circle of radius r with a unifirm speed v then the velocity vector is​

Answer 1

Answer:

what I don't understand

Answer 2

Answer:

Here, a particle moves along a circular path of radius r with uniform speed v.

Thus the angular velocity is:

ω=

r

v

The angle described by the radius vector is:

θ=ωt

For t=1 s,

θ=ω=

r

v

=vr
