Answer:

F = 20 N

Step-by-step explanation:

Given that,

Mass of the football, m = 2 kg

Initial speed, u = 0

Final speed,v = 5 m/s

The time of contact, t = 0.5 s

We need to found the average force applied by the footballer on the football. We can find it using the formula.


F=(m(v-u))/(t)\\\\F=(2* (5-0))/(0.5)\\\\F=20\ N

So, the required force is 20 N.
