Long separated by cruel fate, the star-crossed lovers raced across the g= rassy field towards each other like two freight trains, one having left = York at 6:36 p.m. travelling at 55mph, the other from Peterborough at 4:=
19 p.m. at a speed of 35mph. The brakes decelerate each train at the ra= te of 1.0 m/s2. Is there a collision? What distance do the trains need = to allow between them to stop at this deceleration? What deceleration d= o the two trains need to have to stop in exactly a distance of 938m?
