Final answer:
The net force on a car with a mass of 1.00 x 10^3 kilograms and an acceleration of 4.5 meters/second² is calculated using Newton's second law of motion (F = ma), resulting in 45 x 10^3 newtons.
Step-by-step explanation:
To calculate the net force on the car, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).
In this case, the mass of the car (m) is given as 1.00 x 103 kilograms and the acceleration (a) is 4.5 meters/second2. By substituting these values into the equation, we find:
F = 1.00 x 103 kg * 4.5 m/s2
F = 4.5 x 103 kg*m/s2
F = 4.5 x 103 N
This value is not one of the options provided. However, if we notice that 4.5 x 103 equals 0.45 x 104, which can also be written as 4.5 x 103, we find that option (c) correctly represents the force in scientific notation.
Therefore, the correct answer is: (c) 45 x 103 newtons.
