A0.89 kg ball is moving horizontally with a speed of 3.8 m/s when it strikes a vertical wall. the ball rebounds with a speed of 1.3 m/s. what is the magnitude of the change in linear momentum of the ball?

The change in momentum, p = -4.539 kg-m/s

Explanation:

It is given that,

Mass of the ball, m = 0.89 kg

Initial speed of the ball, u = 3.8 m/s

Final speed of the ball, v = -1.3 m/s (as it rebounds)

Let p is the change in linear momentum of the ball. We know that the linear momentum is equal to the product of mass and velocity. It is given by :

p = -4.539 kg-m/s

So, the change in linear momentum of the ball is 4.539 kg-m/s. Hence, this is the required solution.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
