Answer:
Explanation:
Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle
torque is zero as , centripetal force passes through axis of rotation that is center.
So work done by centripetal force = 0
So work done by tension on M = 0
100 meters in 9.92 seconds,
=distance/time
=100m/9.92s
=10.0806 m/s
