Friction, engine thrust, normal reaction and weight, these are the forces acting on motor when it moves in a straight line
C i’m pretty sure. correct me if i’m wrong :)
Answer:

Distance = 6m
Time = 3 seconds
Coefficient of kinetic friction = 0.3
We begin by calculating for acceleration
Which was gotten as 1.33 m/s sq
