What magnitude net force is required to accelerate a 1200-kg car uniformly from 0 m/s to 27.0 m/s in 10.0 s?
A) 444 N
B) 1620 N
C) 3240 N
D) 4360 N
E) 11800 N

Using the formula, 
$F_{net}=ma$
Where 
$m=1200 kg$
$a=\frac{\Delta v}{\Delta t}=\frac{27.0 m/s-0 m/s}{10.0 s}=2.70 m/s^2$
Substituting the values, we get
$F_{net}=1200 kg 	imes 2.70 m/s^2= \boxed{3240 N}$
