A red ball of mass 4kg is moving at 8 m/s and collides with another 2 kg stationary green ball. After the collision, the green ball starts moving in the same direction of the red ball with a velocity
of 5 m/s. Neglecting friction, the momentum of the red ball after the
collision is __ kg. m/s. *

explanation:

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
