The car's acceleration is equal to [tex]4.5\frac{m}{s^{2}}[/tex] to the east.
Why?
To calculate the car's acceleration, we need to use the given information about its mass and the force applied on it. We can use the following formula:
[tex]Force=mass*acceleration\\\\6570N=1500Kg*acceleration\\\\acceleration=\frac{6750N}{1500Kg}=4.5\frac{m}{s^{2}}[/tex]
Hence, we have that the car's acceleration is equal to [tex]4.5\frac{m}{s^{2}}[/tex] to the east.
Have a nice day!
