If the distance s travelled by a particle in time t is given by s=t^2-2 t+5 , then its acceleration is

Options

  1. A0
  2. B1
  3. C2
  4. D3

Correct answer

C. 2

Step-by-step solution

Given, s=t^2-2 t+5 On differentiating w.r.t., t we get d s d t =2 t-2 Again differentiating, we get d^2 s d t^2 =2
