Answer:
the magnitude of the car's acceleration is 0.2333 m/s^2.
Step-by-step explanation:
To find the magnitude of the car's acceleration, we can use the formula:
a = F/m
where a is the acceleration, F is the net force acting on the car, and m is the mass of the car.
In this problem, F = 10.5 N and m = 45 kg. Substituting these values into the formula, we get:
a = 10.5 N / 45 kg
a = 0.2333 m/s^2
Therefore, the magnitude of the car's acceleration is 0.2333 m/s^2.
