A person weighing `60kg` In a small boat of mass `140 kg` which is at rest, throws a `5 kg` stone in the horizontal direction with a velocity of `14m//s^(-1)`. The velocity of the boat immediately after the throw is (in `m//s`)

A boat of mass 40kg is at rest. A dog of mass 4kg moves in the boat with a velocity of 10m//s . What is the velocity of boat (nearly)?

A boat of mass 50kg is at rest. A dog of mass 5kg moves in the boat with a velocity of 20m//s . What is the velocity of boat?

A girl of mass 50 kg jumps out of a boat of mass 300 kg with horizonal velocity of 3ms^-1 . With what velocity does the boat begin to move backwards?

A body of mass 2 kg, travelling at 4 m/s makes a head-on collision with a body of mass 1 kg travelling in the opposite direction with a velocity of 2 m/s, the velocities of the two bodies after collision are

A girl of mass 50 kg jumps out of a rowing boat of mass 300 kg on to the bank, with a horizontal velocity of 3 m/s. With what velocity does the boat begin to move backwards ?

A man of mass 62 kg is standing on a stationary boat of mass 238 kg. The man is carrying a sphere of mass 0.5 kg in his hands. If the man throws the sphere horizontally with a velocity of 12 ms^(-1) , find the velocity with which the boat will move (in magnitude)
