When a 4kg rifle is fired, the 10g bullet receives an acceleration of 3×106cm/s2. The magnitude of the force acting on the rifle (in newton) is
Many people are familiar with the fact that a rifle recoils when fired. This recoil is the result of action-reaction force pairs. A gunpowder explosion creates hot gases that expand outward allowing the rifle to push forward on the bullet. The bullet pushes backwards upon the rifle. The acceleration of the recoiling rifle is
From a rifle Mass 4 kg, a bullet of mass 50g is fired with an initial velocity of 35m/s. Calculate the initial recoil velocity of the rifle
From a rifle of mass 4kg, a bullet of mass 5kg is fired with a initial velocity of 20m/s.Calculating initial velocity of the rifle?
