A 50 kg ice skater is moving at 5m/s when she grabs the loose end of the rope,the opposite end of which is tied to a pole.She then moves in a circle of radius 1M around the pole.What is the force exerted by the rope on her arms?
I think F=M*V^2/r =250N am I right?
The ice skater is moving in a circle with constant velocity
Centripetal force= F= ...
The solution calculates the centripetal force-force exerted by the rope on the ice skater's arms.
