Assume that the brakes in your car create a constant deceleration of 3.4 m/s2 regardless of how fast you are driving.
calculate the stopping distances for initial speed of 38 m/s .
so, i put it in the equation vf^2=vi^2+2aδx and i got the answer 212.35 but they only want 2 significant figures which means i can only put 21 but its wrong so i ma a little
