In a demolition derby, two cars start from rest at opposite ends of a track. At exactly the same instant they begin to accelerate towards each other in a straight line. Car A accelerates at a rate of aA = 3.0 m/s2 , while Car B accelerates at a rate of aB = 4.0 m/s2 in the opposite direction. After 6.5 s the cars collide. Please use a coordinate system where Car A is travelling in the positive direction. a)(8...

A science student is riding on a flatcar of a train traveling along a straight horizontal track at a constant speed of 10.2 m/s. The student throws a ball along a path that she judges to make an initial angle of 54.5� with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does the ball rise? (Neglect air resistance.)
