Answer :
Final answer:
To find the magnitude and direction of the net force acting on the car, we use Newton's second law of motion and convert the car's velocity from km/h to m/s. From there, we can calculate the net force and determine its magnitude and direction.
Explanation:
To determine the magnitude and direction of the net force acting on the car, we need to use Newton's second law of motion which states that the net force is equal to the product of the mass and acceleration. In this case, the car is slowing down, so its acceleration is negative.
First, we convert the car's velocity from km/h to m/s: 116 km/h = 32.2 m/s. Then, we can use the equation F_net = m * a to calculate the net force: F_net = 1485 kg * (-32.2 m/s)/(10.25 s) = -4659.23 N.
The magnitude of the net force is 4659.23 N, and since the car is traveling south and slowing down, the direction of the net force is north.
