Question

a particle is completing 5 revolution per second in a circle of radius 6 cm.calculate its linear velocity and the centripetal acceleration acting on it.

Answer 1

change 5 rev to 10PI rad

w=10PI rad/sec


velocity=w*radius

centripetal acceleartion= w^2 * r

Answer 2

C = 6.28*r = 6.28 * 6cm = 37.68cm/rev.

V = 5rev/s * 37.68cm/rev = 188.4cm/rev = Linear velocity.
