JEE Main 2021 — Laws Of Motion Question with Solution
From: JEE Main 2021 (Online) 24th February Evening Shift
Question
A particle is projected with velocity v0 along x-axis. A damping force is acting on the particle which is proportional to the square of the distance from the origin i.e. ma = x2. The distance at which the particle stops :

Correct answer
A
Step-by-step explanation
Given, speed of projection = v0
Damping force, F = ma = x2
a = x2 / m
Also,
Integrating both sides, we get
Damping force, F = ma = x2
a = x2 / m
Also,
Integrating both sides, we get
