Question

ring of radius 0.5 metre and
kg 10 kg is rotating about its diameter angular velocity of 20 Radian per second its kinetic energy is​

Answer 1

Answer:

Data

radius = 0.5 m

mass = 10kg

angular velocity = 20 rad/sec

Solution.

Step 1

V =rw (w = angular velocity)

V =0.5×20

V = 10 m/s (V = linear velocity)

Step 2

K.E = 1/2mV²

= 1/2×10×100

K.E = 500 J.

Hope you get it clearly!
