I have: an object starts from rest and moves with a uniform acceleration of 10m/s² for 5 seconds it then uniformly retards at 10 m/s² to again come to rest in next 5 seconds its position time graph will be? (Answer: Option 3)
But, the object is retarding later. Won't the slope of the graph go down? Also, using the equation of motion (s=ut + 1/2at² ) both have the same distances i.e., 125m. Isn't options 1 the answer?
