. A jeep is traveling on a straight road and it leaves ajunction at time t = 0 second. It is then accelerates at 4 m/s 2for 4 seconds. Suddenly, when the driver shifting the gears, thereis no acceleration of the jeep for 1 second. After that, it iscontinue to accelerates at 5.5 m/s 2 for 5 seconds and maintain thespeed it reached. On the other hand, a car leaves at the samejunction as jeep at time t = 0 second. The car accelerates fromrest to 25 m/s in 20 seconds and then maintain the speed of 25 m/s.The car passes the jeep as they both pass a traffic light. (i)Sketch speed vs. time graph to illustrate the motion of the jeepand the car by using same diagram. (ii) Find the distanceof the traffic light from the junction. (iii) After 4seconds from the constant speed, both jeep and car decelerates torest in T seconds. Determine the value of T. (iv) If thecar in this motion has zero speed at some instant in time, is theacceleration necessarily to be zero at the same instant? Prove youranswer with some calculation example. (3
