Quizplus · Accepted Answer

We can use the equation F = ma, where F is the net force, m is the mass of the car, and a is the acceleration of the car.

The acceleration of the car is:

a = (v_f - v_i) / t
a = (27.0 m/s - 0 m/s) / 11 s
a = 2.45 m/s^2

So, the net force required to accelerate the car is:

F = ma
F = (1200 kg)(2.45 m/s^2)
F = 2940 N

Therefore, the best choice is C, 3240 N, which is the closest value to 2940 N.
