Motion in A Straight Line question

2025 · 3 Apr · Shift 2 · Q53

JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
A particle moves along the xxx-axis and has its displacement xxx varying with time t according to the equation: x=c0(t2−2)+c(t−2)2x=\mathrm{c}_0\left(\mathrm{t}^2-2\right)+\mathrm{c}(\mathrm{t}-2)^2x=c0​(t2−2)+c(t−2)2 where c0\mathrm{c}_0c0​ and c are constants of appropriate dimensions. Then, which of the following statements is correct?
  1. A
    the acceleration of the particle is 2(c+c0)2\left(c+c_0\right)2(c+c0​)
  2. B
    the acceleration of the particle is 2c02 c_02c0​
  3. C
    the acceleration of the particle is 2 c
  4. D
    the initial velocity of the particle is 4c4 c4c
