DON'T MISS THE 2 PRACTICE PROBLEMS ON RELATIVE MOTION AND DIFFERENT SITUATIONS OF OPTIMUM SPEED AT THE END OF THE VIDEO. 
Q :Questions 32 to 35 are based on the following physical situation.
 Two particle A and B are moving towards each other on a straight line with equal speeds 5 m/s.At an instant that is assumed t = 0 s. distance between the particles is 100 m. It is desired to move another particle C always maintaining a distance 40 m from the particle A and 30 m from the particle B.
 1. When and for how long can the particle C fulfill the given condition?
 (a)   (b)   (c)   (d)  
 2. What is speed of the particle C at the instant t = 5 s ?
 (a) 3.5 m/s                                (b) 4.8 m/s
 (c) 5 m/s                                 (d) 6 m/s
 3. What is modulu11 of acceleration of the particle C at the instant t=5s?
 (a)   (b)   (c)   (d)  
 4. At  the  instant,  when  the  line  joining  locations  of  A  and  B  is perpendicular to the line joining  locations of B and C. what arc the magnitudes of velocities of C relative to A and B respectively?
 (a) 0 m/s and 5 m/s                     (b) 0 m/s and 10 m/s
 (c) 3.75 m/s and 0 m/s                 (d) 3.75 m/s and 10 m/s

 LEARN THE BEST WAY TO COUNTER THESE PROBLEMS IN EXAM CONDITIONS. WHAT'S THE SHORTEST WAY TO COUNTER THESE PROBLEMS?  THE ANSWER LIES IN THE LUCID EXPLANATION OF CONCEPT/SOLUTION IN THE VIDEO . IN THIS VIDEO WE PRESENT AN EXAM ORIENTED APPROACH FOR KINEMATICS OBJECTIVE 32 TO 35 PASSAGE FROM CHAPTER - 1  SOLVED FROM THE BOOK "PATHFINDER PHYSICS"👇.THE TWO PRACTICE PROBLEMS ARE CHOSEN CAREFULLY IN INCREASING LEVEL OF DIFFICULTY FROM JEE ADVANCED AND OLYMPIADS . WHAT WE CAN EXPECT IN FUTURE ON THIS TOPIC ?
