Question

A train which is traveling at 80 mi/hr applies its brakes 1 mile before the
intersection. Its velocity is reduced to be 60 mi/hr as it passes a point one half mile after.
A car, on the other road, moving at 50 mi/hr was 1.3 miles away from the intersection the
moment the train was 1 mile before the intersection. Calculate the constant acceleration
that the car must have in order to beat the train to the intersection by 4 seconds and find
its velocity as it reaches the crossing.*
