Question: a train which is traveling at 90 mihr applies its...

Question details

A train which is traveling at 90 mi/hr applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 69 mi/hr as it passes a point 1/2 mi beyond A A car moving at 46 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 athat the car must have in order to beat the train to the crossing by 4.7 sec and find the velocity v of the car as it reaches the crossing.
