suppose that the net external force exerted on the car is 350 N parallel to the ground, and the mass of the car is 1800 kg. What is its acceleration?
To find the acceleration of the car, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The equation is given as:
F = m * a
Where:
F is the net force on the object,
m is the mass of the object,
a is the acceleration of the object.
In this case, the net force on the car is 350 N (parallel to the ground) and the mass of the car is 1800 kg. Plugging these values into the equation, we have:
350 N = 1800 kg * a
To solve for the acceleration (a), we can rearrange the equation:
a = 350 N / 1800 kg
Now we can calculate the acceleration:
a = 0.194 m/s^2
Therefore, the acceleration of the car is approximately 0.194 meters per second squared.
