When we pass from crossing on a road we all see traffic lights blinking there. A traffic controller set the timmings of traffic lights in such a way that all lights are not green at the same time or specially not in the rush hour, because it can create chaos or problems. So, he take the timings of nearby places in same area and calculate LCM of all traffic stops and he easily manage the traffic by increase the duration or set at different times. There are two traffic lights on a particular highway which shows green light on time of 90 seconds and 144 seconds respectively. Evaluate the HCF of the timings of two green Lights.

A car waiting at a traffic light starts to move with a constant acceleration of 2.0 m//s^(2) when the light truns green. Two second later, a truck moving in the same direction passes the light at a constant speed of 25 m//s and soon passes the car. Soon the car passes the truck: (a) How long after the car starts do the two overtakings occur ? (b) How far from the light does each take place?
