A particle moves along x - axis as x = 4 t - 2 + a t - 2 2 . Which of the following is true?

Question

A particle moves along x - axis as x = 4 t - 2 + a t - 2 2 . Which of the following is true?, The initial velocity of the particle is 4 m s - 1, The acceleration of particle is 2 a, The particle is at origin at t = 0, None of the above

MARKS App · Accepted Answer

Given, x = 4 t - 2 + a t - 2 2 v = d x d t = 4 + 2 a t - 2 At t = 0 , v = 4 1 - a Acceleration a = d 2 x d t 2 = 2 a
