Surfing For Physics Formulas For Acceleration?

Nancy asks…What physics formula can be used for this question? A train 350 m long is moving on a straight track...?A train 350 m long is moving on a straight track with a speed of 84.6 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 16.0 km/h. Assuming constant acceleration, determine how long the train blocked the crossing. Disregard the width of the crossing.

I cant figure out a formula for this one either. Any help would be
