The magnitude of the change in momentum is twice the initial momentum 2mV.

Momentum is the same as the mass of an item elevated by using its pace and is equal to the pressure required to bring the item to a stop in a unit length of time.

Calculation:-

mass of the ball = m

Let the initial velocity coming the vertical wall is = +v

Final velocity bouncing back from the wall = - V

momentum = mv

Change in momentum = m ( final velocity - initial velicity)

= m ( -V - V)

= - 2mV

Only magnitude = 2mV.

Linear momentum, translational momentum, or true momentum is manufactured from the mass and speed of an item. it's far a vector quantity, possessing a magnitude and a course. If m is an object's mass and v is its velocity. Momentum is a dimension of mass in movement. How tons mass is in how much movement. additionally, it is given the symbol p.
