Answer:
Change in momentum will be -2.61 kgm/sec
Explanation:
We have given mass of the rubber ball m = 0.30 kg
Velocity of the ball before the impact [tex]v_1=4.5m/sec[/tex]
Velocity of ball after impact [tex]v_2=-4.2m/sec[/tex] ( negative sign is due to opposite direction of motion )
Change in momentum is given by [tex]m(v_2-v_1)=0.3\times (-4.2-4.5)=0.3\times =0.3\times -8.7=-2.61kgm/sec[/tex] ( negative sign shows the direction of change in momentum )
