A bowling ball has a mass of 5 kg hits a wall going 7 m/s and rebounds at a speed of 2 m/s. What was the impulse applied to the bowling ball?

Respuesta :

Impulse is given by

[tex]Impulse = P_f - P_i[/tex]

[tex]Impulse = 5*2 - (5*-7)[/tex]

[tex]Impulse = 10 + 35[/tex]

[tex]Impulse = 45 kg m/s[/tex]

So impulse given by the ball will be 45 kg m/s.

the answer is 45......................
