Expression and their feature/principle

Question

If s, v, t, F, m and a represent displacement velocity time, force mass and acceleration respectively.

Match List –I (Expression) with List – II (Feature/Principle) and select the correct answer.

             List – I                List – II

 A. V = 6t² – 9t             1. Constant acceleration

 B. V = 9t + 12              2. Variable acceleration

 C. S = 4t                      3. D’ Alembert’s principle

 D. F – ma  = 0             4. Uniform motion

 Codes:          A    B    C    D

              (a)    2    1     4    3

              (b)    4    3     2    1

              (c)    2    3     4    1

              (d)    4    1     2    3
