Motion in A Straight Line question

2023 · 15 Apr · Shift 1 · Q46

JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
The position of a particle related to time is given by x=(5t2−4t+5)mx=\left(5 t^{2}-4 t+5\right) \mathrm{m}x=(5t2−4t+5)m. The magnitude of velocity of the particle at t=2st=2 st=2s will be :
  1. A
    14 ms−114 \mathrm{~ms}^{-1}14 ms−1
  2. B
    16 ms−116 \mathrm{~ms}^{-1}16 ms−1
  3. C
    10 ms−110 \mathrm{~ms}^{-1}10 ms−1
  4. D
    06 ms−106 \mathrm{~ms}^{-1}06 ms−1
