how much must a car produce to drive 150 km if an average force of 500 N must be maintained to overcome friction?
work (Joules) = force (Newtons) * distance (meters)
46600
To determine the work done by the car's engine, which is required to overcome friction and drive a distance of 150 km, we need to use the formula:
Work = Force × Distance
First, let's convert the distance from kilometers to meters, as the SI unit of force is Newton and distance is measured in meters:
150 km = 150,000 meters
Now we can calculate the work done:
Work = Force × Distance
= 500 N × 150,000 meters
Multiply these values to find the work:
Work = 75,000,000 joules (J)
Therefore, the car's engine must produce 75,000,000 joules of work to drive 150 km while maintaining an average force of 500 N to overcome friction.
