A body travels 102.5 ~m in n ^ th second and 115.0 ~m in ( n +2)^ th second. The acceleration is :

Options

  1. A6.25 ~m / s ^2
  2. B12.5 ~m / s ^2
  3. C9 ~m / s ^2
  4. D5 ~m / s ^2

Correct answer

A. 6.25 ~m / s ^2

Step-by-step solution

aligned & Given, 102.5= u + a 2 (2 n -1) & & 115= u + a 2 (2 n +3) & 102.5= u + an - a 2 & & 115= u + an + 3 a 2 & 12.5=2 a a =6.25 ~m / s ^2 aligned
