Answer: The trip takes 
Explanation:
Velocity
is the variation of the position of a body (distance traveled
) with time
:
In this case, the car travels a distance
at a velocity
and we need to find the time it takes the trip.
Isolating
:

Finally:

Explanation:
Using Kinematics,
we have a = (v - u) / t.
Therefore a = (36m/s - 22m/s) / 5s = 2.8m/s².
