JEE Main 18 March 2021, Shift 1, Physics Q5

Question 5 of 90 in this shift, Physics question 5 of 30, Section A.

The position, velocity and acceleration of a particle moving with a constant acceleration can be represented by :

The figure, in words

Each option shows three graphs (position vs t, velocity vs t, acceleration vs t).
  1. (1)[figure: x(t) straight line with positive intercept rising; v(t) straight line rising from positive intercept; a(t) constant horizontal line]
  2. (2)[figure: x(t) convex curve rising; v(t) straight line falling; a(t) constant horizontal line]

Question text from the official JEE Main paper published by NTA; answer from the final answer key. Chapter, topic and idea tags, difficulty and skill are Lumi’s. This question needs a figure we do not reproduce; it is described in words above. Lumi analyses 42 of the 174 JEE Main shifts held from 2017 to 2026.
