Question

The displacement $S$ of a particle is proportional to the first power of time $t$, i.e., $S\propto t$; then the acceleration of the particle is

• A. Infinite
• B. Zero
• C. A small finite value
• D. A large finite value

Answer 1

The correct option is B Zero

Let $S=kt+c$
Differentiating $S$ twice to get acceleration, we see that
$\frac{d^{2}S}{d{t}^2}=0$
$\therefore$ Acceleration comes out to be zero.
