Question
If A,B,C are the maximum velocities of the particles moving according to the law respectively then the ascending order of A,B,C is
 A, B, C
 C, B, A

 B,C,A
Hint:
The quantity ds/dt is called the derivative of s with respect to t, or the rate of change of s with respect to t. It is possible to think of ds and dt as numbers whose ratio ds/dt is equal to v; ds is called the differential of s, and dt the differential of t.
The correct answer is: B,C,A
