The distance (s) travelled by a particle in time \(t\) is given by \(s=4 t^2+2 t+3\). The velocity of the particle when \(t=3\) seconds is
- A 26 unit/sec
- B 20 unit/sec
- C \(24 \mathrm{unit} / \mathrm{sec}\)
- D 30 unit/sec
Answer & Solution
Correct Answer
(A) 26 unit/sec
Step-by-step Solution
Detailed explanation
Velocity \(=\frac{d s}{d t}=8 t+2\) Velocity at \(t=3\) seconds is \(v=24+2=26 \mathrm{unit} / \mathrm{sec}\).
