Consider a cart of mass M on a frictionless surface that can hold a full tank of water with mass M.A fire-hose sprays water with a constant ejection speed `V_(w)` at a constant mass rate `r=(dm)/(dt)` and at an angle `theta` relative to the horizontal.

A canon of mass M is mounted on an east west frictionless railway track. The barrel of cannon faces the north east direction at an angle of 45^(@) with the vertical. The canon fires a shot of mass M with a speed V relative to the barrel.

A rocket of initial mass 6000kg ejects mass at a constant rate of 16kg//s with constant relative speed of 11m//s What is the acceleration of the rocket one mnute after blast ?

A rocket of initial mass 6000kg ejects mass at a constant rate of 16kg//s with constant relative speed of 11km//s What is the acceleration of the rocket one minute after blast ?

A block of mass m is on the smooth horizontal surface of a plank of mass M The plank is on smooth horizontal surface Now, a constant horizontal force F acts on M. Now, for a person standing on the ground:

A loaded spring gun, initially at rest on a horizontal frictionless surface, fires a marble at angle of elevation theta. The mass of the gun is M, the mass of the marble is m, and the muzzle velocity of the marble is v_0 . What is the final motion of the gun ?
