Read the following and answer questions from (i) to (v) Aditya started driving his car. He increases the speed till 4 seconds and then he kept his card in constant speed for 6 seconds. Then after he decreased the speed of the car upto another 6 seconds. After reaching at the starting place, he draws the speed-time graph of his 16 seconds driving as shown in figure: (i) What type of motion is represented by OA ? (1 Point) (a) uniform velocity (b) uniform acceleration (c) negative acceleration (d) no acceleration

Explanation:
a) Image of the graph is attached below.
b) The speed vs time graph for the situation is plotted as given in the image. It is given that Aditya starts from rest and keeps increasing his speed till 4 seconds. So this will be an accelerated motion with a positive slope.
c) The time from 10 to 16 is when he starts decreasing the speed of the car. So this will be decelerated motion.
For option d,e and f. Its actually not possible to find the value of acceleration and retardation from the given data. Maybe you should include some more details also to the question.
Let me try to give an generalized answer for d, e, f.
