Question 1 :
<font>A truck and a car moving with the same kinetic energy are brought to rest by the application of brakes which provide equal retarding forces. Which of them will come to rest in a shorter distance?</font></p>

Question 2 :
<font>Consider the following statements A and B. Identify the correct choice in the given answers:</font></p> <p align="justify"> <font>A. In a one dimensional perfectly elastic collision between two moving bodies of equal masses, the bodies merely exchange their velocities after collision</font></p> <p align="justify"> <font>B. If a lighter body at rest suffers perfectly elastic collision with a very heavy body moving with a certain velocity, then after collision both travel with same velocity</font></p>

Question 3 :
<font>When two spheres of equal masses undergo glancing elastic collision with one of them at rest, after collision they will move:</font></p>

Question 4 :
A block weighing 10 N travels down a smooth curved track <em>AB</em> joined to a rough horizontal surface. The rough surface has a friction coefficient of 0.20 with the block. If the block starts slipping on the track from a point 1.0 m above the horizontal surface, then it would move a distance <em>S</em> on the rough surface. The value of <em>S</em> is (<em>g</em> = 10 ms^–2).<img style='object-fit:contain' style="max-width:240px;" src="https://storage.googleapis.com/teachmint/question_assets/JEE%20Main/5f16bf9abfef6349df00fcfa"/>

Question 5 :
A particle initially at rest at the highest point of a smooth vertical circle is slightly displaced. It will leave the circle at a vertical distance <em>h</em> below the highest point.
