JEE Main 4 April 2024, Shift 1, Physics Q33

Question 33 of 90 in this shift, Physics question 3 of 30, Section A.

A wooden block, initially at rest on the ground, is pushed by a force which increases linearly with time t. Which of the following curve best describes acceleration of the block with time :

The figure, in words

Four a-t graphs as options, each with axes a (vertical) and t (horizontal), origin labelled (0, 0).
  1. (1)[figure: graph of a vs t, curve starting at origin, nearly flat then rising increasingly steeply (convex)]
  2. (2)[figure: graph of a vs t, straight line through origin (0, 0) with positive slope]Official answer
  3. (3)[figure: graph of a vs t, straight line with positive slope and positive intercept on the a-axis]
  4. (4)[figure: graph of a vs t, horizontal straight line at constant a > 0]
