Question

it is difficult to pull a 50 kg person but if he said on a cycle is become easier how it is possible​

Answer 1

1. Friction :- The sliding friction is more than rolling. Therefore it is more difficult to pull than riding it on cycle.

3. Torque :- Because on the cycle we apply force with legs that is converted to torque and this torque is then converted to force which causes motion. But the Output force is more than the applied force. Same as Lever arm or see-saw.

Answer 2

Answer:

When we try to pull a 50 kg man its hard for us but if he is on a cycle it is much easier to pull him because when he sits on cycle the wheels pull the weight off by its curve it is easy for us to pull the man and due to the circular shape of wheel acts against the constant friction.
