calculate the distance it traveled before it is brought to rest from 44 km/h if the speed of a truck going south is reduced from 80 km/h to 44 km/h in a distance of 250 m.
change velocities to m/s.
Then vf^2=vi^2+2ad. find a from the change 80>44.
then use that a for the original q from 44>zero, find d.
