If the distance \(s\) travelled by a particle in time \(t\) is given by \(s=t^2-2 t+5\), then its acceleration is
- A 0
- B 1
- C 2
- D 3
Answer & Solution
Correct Answer
(C) 2
Step-by-step Solution
Detailed explanation
Given, \(s=t^2-2 t+5\) On differentiating w.r.t., \(t\) we get \(\frac{d s}{d t}=2 t-2\) Again differentiating, we get \(\frac{d^2 s}{d t^2}=2\)
