JEE Main 4 April 2025, Shift 2, Physics Q30

Question 30 of 75 in this shift, Physics question 5 of 25, Section A.

The displacement xx versus time graph is shown below. (A) The average velocity during 0 to 3 s is 10 m/s (B) The average velocity during 3 to 5 s is 0 m/s (C) The instantaneous velocity at t = 2 s is 5 m/s (D) The average velocity during 5 to 7 s and instantaneous velocity at t = 6.5 s are equal (E) The average velocity from t = 0 to t = 9 s is zero Choose the correct answer from the options given below :

The figure, in words

Displacement (m) vs time (s) piecewise-linear graph: O(0,0) down to A(1,-5), up through B(2,0) to C(3,5), flat from C to D(5,5), up to E(6,10), down through F(7,0) to G(8,-5), up to H(9,0).

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.
