A ball of mass m strikes a wall perpendicularly with a speed v, and it bounces off the wall perpendicularly with a speed v 5 . What is the magnitude of the impulse delivered to the wall by the ball?

Respuesta :

Answer:

Explanation:

Given

mass of ball is m

initial velocity of ball is [tex]v[/tex]

Final velocity of ball is [tex]v_5[/tex]

Impulse is the change in momentum of an object when an external force is applied for a given interval of time.

Initial momentum [tex]P_i=mv[/tex]

Final momentum [tex]P_f=mv_5[/tex]

[tex]Impulse=P_f-P-i=m(v_5-v)[/tex]
