Question

A 0.45 kg soccer ball is kicked through the air. What amount of impulse, in kg*m/s, is needed to cause the soccer ball to travel at 15 mph?

Answer 1

Answer #1

Impulse = change in momentum

But initial momentum is zero .

So

Impulse= mv

I= 0.45× 15× 0.447 kg m/s

I=3.0171 kg m/s

Answer 2

A soccer ball of mass 0.36 kg is rolling with velocity <0, 0, 1.5> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.7 N.s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.34 N in the direction opposite to the direction of the ball's time 1.5 s after you kick it, assuming that the ball is at the origin at the moment it is kicked....
