Question

A car is travelling with uniform motion with a total frictional resistance of 2.8 × 103 N acting in a direction opposite to the motion of the car. What is the force acting on the car in the direction of motion?[1 K, 1 Inq]

Answer 1

For travelling with uniform motion

$$ma=F-F_f=0$$

$$F=F_f=2.8 \cdot 10^3 \ N$$
