a 1000 kg car has a motor that exerts 1500 N of force to move it forward. a frictional force of 400 N opposes it's forward motion. calculate the acceleration of this car
Indicate your subject in the "School Subject" box, so those with expertise in the area will respond to the question.
To calculate the acceleration of the car, you can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be represented by the equation:
Fnet = ma
Where:
Fnet is the net force acting on the object,
m is the mass of the object, and
a is the acceleration.
In this case, the net force acting on the car is the difference between the motor force and the frictional force:
Fnet = Fmotor - Ffriction
Now, we can substitute the given values into the equation:
Fnet = 1500 N - 400 N
Fnet = 1100 N
Since we have the net force, we can calculate the acceleration by rearranging the formula:
a = Fnet / m
a = 1100 N / 1000 kg
a = 1.1 m/s^2
Therefore, the acceleration of the car is 1.1 m/s^2.
