JEE Main 2012 — Motion In One Dimension Question with Solution
JEE Main 2012 (26 May Online)
Question
A ball is dropped vertically downwards from a height above the ground. It hits the ground inelastically and bounces up vertically. Neglecting subsequent motion and air resistance, which of the following graph represents variation between speed and height correctly?

Correct answer
D
Step-by-step explanation
When a ball hits the ground vertically then some of its energy is lost due to which it bounces back to lesser height with less velocity. The energy of the ball keep on decreasing with time and finally it become zero. Due to this variation of velocity with height can be represented as follows :
