If a particle moves according to the law

s = 6{t^2} - \frac{{{t^3}}}{2}

, then the time at which it is momentarily at rest is

View answer and explanation

Correct option: C

t = 0,\;8

Option C (

t = 0,\;8

) is correct because the particle is momentarily at rest when its velocity (first derivative of position) is zero.
