1. Two sprinters P & Q both start the race at the same time but from different starting lines on the track. The track is developed in such a way that both sprinters reach the line XY, as shown in the image above at the same time. Sprinter P has a constant acceleration of 1.6 m/s2 from the start line to the line XY. Sprinter Q has a constant acceleration of 1.2 m/s2 from the start line to XY. a) Calculate the time taken by the sprinters to reach line XY. b) Find the speed of each sprinter at this line. c) Calculate the distance between the starting lines for sprinters P and Q.
