If a 2 kg ball is moving at 6 m/s to the right and then hits a wall and bounces back at - 4 m/s (left), what is the change in momentum (in kg*m/s)?

The change in momentum (in kg*m/s)

Explanation:

The change in momentum is equal to

Final Momentum - Initial Momentum

As we know

Momentum is equal to the product of mass and velocity

M = m * v

Thus, change in momentum

here m1 = m2 = 2 Kg

Substituting the given values in above equation we get -

kg m/s

true
