Question: a train which is traveling at 81 mihr applies its...

Question details

A train which is traveling at 81 mi/hr applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 62 mi/hr as it passes a point 1/2 mi beyond A. A car moving at 38 mi/hr passes point B at the same instant that the train reaches point A. In an unwise effort to beat the train to the crossing, the driver steps on the gas. Calculate the constant acceleration a that the car must have in order to beat the train to the crossing by 4.3 sec and find the velocity v of the car as it reaches the crossing.
