Question

A 0.60 kg soccer ball at rest is kicked by a player who has a mass of 50.0 kg. The final speed of the soccer ball after being kicked is 10.0 m/s. Find the final momentum of the soccer ball. A) 6.0 kg·m/s B) 30.0 kg·m/s C) 50.0 kg·m/s D) 150.0 kg·m/s

Answer 1

Final momentum of the soccer ball is 6
`(kg\,m)/(s)`

Step-by-step explanation:

The linear momentum of an object is defined as the product of its mass times its velocity (p = m * v). Therefore in this case the initial momentum of the ball is zero (it is at rest so velocity is zero), but the final momentum after being kicked, is: p = 0.6 kg * 10 m/s = 6 kg m/s

which agrees with answer A of your list.
