For a particle moving along a straight line, the displacement is $x = P t^{3} + Q t^{2} + Rt + S$ . The ratio of its initial acceleration to its initial velocity depends on:

Options:

Answer:

Solution:

$v (0) = R$ and $a (0) = 2 Q$ , so the ratio is $\frac{2 Q}{R}$ , depending only on $Q$ and $R$ . Option B.
