Explanation:
The equation for acceleration is
v = 13.9 m/s
But that still doesn't give us anything for the time, which is the denominator of the acceleration equation. We have to find it. Since this is one-dimensional travel, use d = rt to find the time it took for the car to travel 35 meters at a rate of 13.9 m/s:
35 = 13.9t and
t = 2.5 seconds. Now we can use that in the acceleration equation:
a = -5.6 m/s/s The negative sign tells us that the car is slowing down, as we would expect it to be when it is traveling at a certain rate and eventually stops.
