Question

Q). If the position of a particle moving laong x-axis as a function of time t isgiven by x = $6t^2$ m (where t is in second), then the acceleration of the particle at t = 5 s is
(1) 60 $m/s^2$
(2) 30 $m/s^2$
(3) 12 $m/s^2$
(4) 5 $m/s^2$

Answer 1

Dear student

$$\begin{gathered} x=6t^2 \\ velocityv=dx/dt=12t \\ acceleration=dv/dt=12whichisindependentoftime \end{gathered}$$
