Question

A particle A moves along a circle of radius R = 50 cm so that it's radius vector r relative to rhe point O rotates with constant angular velocity 0.04 rad/ s then modulus of the velocity of the particle and the modulus of its total acceleration will be

Answer 1

V= 2wR

= 2×0.40×0.5

=0.4

a =v×v/r

=0.32
