determine the net force required to accelerate a 2160 kg ford expedition from 0 to 27 m/s (60 mph) in 10.0 seconds

You can use a basic equation to find acceleration V=Vo+at. You initial velocity is 0 so it would be 27=0+a10. Diving ten gives you the acceleration of 2.7m/s.
F=ma so F=(2160)(2.7)=5832N

a=(v1-v2)/t
   =(27-0)/10
    =2.7m/s^2
now force=mass * acceleration
                 =2160*2.7
                 =5832N
