Answer: 100 m
Explanation:
Initial speed(u) = 40 m/s
Final speed(v) = 0 m/s
Acceleration = v-u/t
=> 0-40/5
=> 8 m/s^2
Displacement= s
=> 2as = v^2-u^2
=> 2(-8)(s) = 0 - (40)^2
=> -16s = -1600
s = 100 m
We can say the vehicle move 100 meters before stopping.
Velocity is the displacement of an object over the amount of time. It is not the same as speed. If an object travels 4 miles forward and then 4 miles back all in one hour, its speed is 8 mph. However, displacement is the difference between the final position and the initial position. So in this case, the average velocity would be 0 because its final and initial positions were the same.
