We can solve the problem by using Newton's second law of motion:
[tex]F=ma[/tex]
where
F is the net force applied to the object
m is the object's mass
a is the acceleration of the object
In this problem, the force applied to the car is F=1050 N, while the mass of the car is m=760 kg. Therefore, we can rearrange the equation and put these numbers in, in order to find the acceleration of the car:
[tex]a= \frac{F}{m}= \frac{1050 N}{760 kg}=1.4 m/s^2 [/tex]
The equation also tells us that the acceleration and the force have same directions: therefore, since the force exerted on the car is horizontal, the correct answer is
B) 1.4 m/s2 horizontally.
