A dog weighing `5kg` is standing on a flat boat so that it is `10` metres from the shore. It walks `4m` on the boat towards the shore and then halts. The boat weighs `20kg` and one can assume that there is no friction between it and water. The dog from the shore at the end of this time is

A man weighing 80 kg is standing at the centre of a flat boat and he is 20 m from the shore. He walks 8 m on the boat towards the shore and then halts.The boat weight 200 kg. How far is he from the shore at the end of this time ?

A dog of mass 10 kg is standing on a flat 10 m long boat so that it is 20 m meters from the shore. It walks 8 m on the boat towards the shore and then stops. The mass of the boat is 40 kg and friction between the boat and the water surface is negligible. How far is the dog from the shore now ?

A man weighting 60 kgis standing at the centre of a flat boat and he is 20 m from the shore. He walks 8 cm on the boat towards the shore and then halts. The boat weights 200 kg How far is the from the shore at the end of this time? [Hints : As the system is free from external force, centre of mass of the system consisting of man and boat must not move.

A 10 kg boy standing in a 40 kg boat floating on water is 20 m away from the shore of the river. If the boy moves 8 m on the boat towards the shore, then how far is he from the shore ? (Assume no friction between boat and water).

A man weighing 70 kg is standing at the centre of a flat boat of mass 350 kg. The man who is at a distance of 10 m from the shore walks 2 m towards it and stops. How far will he be from the shore? Assume the boat to be of uniform thickness and neglect friction between boat and water?
