A car starts from rest and travels for 5.0 s with a constant acceleration of -1.5 m/s^2. What is the final velocity of the car?

Final velocity

Distance covered

Explanation:

If an object having initial velocity u is applied an acceleration of a for t time, it's final Velocity v is given by v = u + at

We have u=o (as the object starts from rest),

t=5 sec and acceleration a

Final velocity v=

Therefore, The final velocity is :-
