(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Force Problem

1. The problem statement, all variables and given/known data

2. A football punter accelerates a football from rest to a speed of 10m/s during the time in which his toe is in contact with the ball (about 0.20sec). If the football has a mass of 0.50kg, what average force does the punter exert on the ball?

2. Relevant equations

so far i have this and can't seem to find the equation(s) but i got some and does not correspond with the correct answer.

a=10ms/^2

t=.20sec

m=.50kg

F= thats what we need for answer

so F=ma

3. The attempt at a solution

but i dont understand how we put our time in an equation to solve for Force, I know im missing something but i don't know what. I have the answer, answer only which does not help at all :P. Thats to check whether we get the correct problem

F = ma

F = 10m/s (.50kg)

F = 5N (?) but answer that was given was 25 N

I want to know how to do it :P even thou teacher gives us answer for homework. Which is the most important thing

I'm stuck with this help

Thank you in advance
