A train begins at the origin and moves at constant speed Vi=10.7 m/s toward another train which is initially at rest at a distance d=168 m from the first train. If the second train has an acceleration of magnitude a2=1.04 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint: use quadratic equation and choose positive time) Select one: O 78.06 m O 111.52 m 44.61 m O 144.97 m O 178.43 m
