Question

A car with a mass of 880 kg is moving on the road with constant velocity. The force exerted by engine is 1600N. What is the frictional force between the road an the car?​

Answer 1

1600 N

Step-by-step explanation:

F-F' = ma.................. Equation 1

Where F = Force exerted by the engine, F' = Frictional Force, m = mass of the car, a = acceleration of the car.

make F' the subject of the equation

F' = F-ma............... Equation 2

Given: F = 1600 N, m = 880 kg, a = 0 m/s (moving with a constant velocity).

Substitite these values into equation 2

F' = 1600+880(0)

F' = 1600 N.
