Two trains, one travelling at 20.8m/s and the other at 76.2 m/s, are headed toward one another along a straight level track. When they are 839 m apart, each engineer sees the other's train and applies the brakes. Assuming both trains have equal magnitude accelerations after the brakes are applied, determine the minimum magnitude of this acceleration () in order to avoid a collision.

A driver is initially traveling 21.1m/s to the right and then slams on the brakes to accelerate at a magnitude of 4.5m/s/s until she comes to a complete stop. If she started applying her brakes at a position of 263m from zero, then where is her final position from zero?
A wide receiver is running along the sideline straight toward the goal at a constant speed. When he is 27 m away from the goal line he catches the ball, but there is a cornerback 12 m behind him moving with a constant speed of vc = 9.0 m/s. What speed should the wide receiver have to make sure he reaches the goal line just as the cornerback reaches him?
