A body of mass 100 grams is tied to one end of a string and revolved along a circular path in the horizontal plane. The radius of the circle is 50 cm. If the body revolves with a constant angular speed of 20 rad/s, find the
1. period of revolution
2. linear speed
3. centripetal acceleration of the body.
Data : m = 100 g = 0.1 kg, r = 50 cm = 0.5 m,
ω = 20 rad/s
1. The period of revolution of the body,
2. Linear speed, v = ωr = 20 × 0.5 = 10 m/s
3. Centripetal acceleration,
ac = ω2 = (20)2 × 0.5 = 200 m/s2
