A cannon is set on a wooden platform fitted with wheels. Total mass of cannon, cannonball, artillery man and platform is M, and that of a cannonball is m. What will be the velocity of the platform when n number of cannonballs are fired horizontally at velocity v?

A gun is mounted on a platform fitted with frictionless wheels. The mass of the platform With the gun, shells and the operator is M. The gun.fires shells one after another with a velocity v in the horizontal direction. If mass of each shell is in, show that the velocity of recoil of the platform after N shells are fired, is V_R = (Nmv)/(M-mN) .

A gun is mounted on a platform fitted with frictionless wheels. The mass of the plarform with the gun, shells and the operator is M. The gun fires shells one after another with a velocity v in the horizontal direction. If mass of each shell is m. show that the velocity of recoil of the platform after N shells are fired, is V_(N) = (Nmv)/((M - mN)) .

A cannon is fixed to the floor of a carriage, which is free to move without friction along a straight track. The combined mass of cannon and carriage is M. The instant cannon fires a cannon ball of mass m with speed u, the velocity of centre of mass of cannon + carriage + ball is

A man of maas m is standing on a platform of maas M kept on smooth ice. If the man starts moving on the platform with a speed v relative to the platform with what velcity relative to the ice does the platform recoil?

A insect of mass m stands on a horizontal disc platform of moment of inertia 1 which is at rest. What is the angular velocity of the disc platform when the insect goes along a circle of radius r, concentric with the disc, with velocity v relative to the disc.

A kid of mass M stands at the edge of a platform of radius R which can be freely rotated about its axis. The moment of inertia of the platform is I . The system is at rest when a friend throws as ball of mass m and the kid catches it. If the velocity of the ball is v horizontally along the tangent to the edge of the platform when it was caught by the kid find the angular speed of the platform after the event.

The system is at rest when a friend throws as ball of mas mand the kid cathces it. If the velocity of the ball is v horiontally along the tangent to the edge of the platform when it was caught by the kid find the angular speed of the platform after the event.

A man of mass m_1 is standing on a platform of mass m_2 kept on a smooth horizontal surface. The man starts moving on the platform with a velocity v_r relative to the platform. Find the recoil velocity of platform.

A man of mass m is standing on a platform of mass M kept on smooth ice. If the man starts moving on the platform with a speed v relative to the platform with what velocity relative to the ice does the platform recoil?
