4. Two particles, A and B, are moving in a straight line. Take this to be the r-axis. At t = 0, particle A is trailing particle B, initially at some distance x behind B. Particle B is accelerating at a constant 2.00 m/s² and particle A is constantly accelerating at 3.00 m/s². Particle A was able to overtake B after B has moved 50.0 m. (a) How long does it take for particle A to overtake B? (b) Initially, how far was A behind B? (c) How fast are the two particles moving as soon as they're at the same position?
