A car of mass 600 kg is travelling at 10m/s. when brakes are applied, it comes to rest in 10 M.
what is the average force exerted by the brakes?

force=ma=600(vfvi)/10sec

Come Again? =S
Can You Write the way to the answer please :)
THANK YOUUU <3 
Force= mass*acceleration.
where
acceleration= change in velocity/time
= (finalvelocityinitialvelocity)/time
= (VfVi)/time 
I Asked My Friend, But Thanks Anyways !!!
=) 
time=10sec ?????
