2/5 The acceleration of a particle is given by $a = -ks^2$, where $a$ is in meters per second squared, $k$ is a constant, and $s$ is in meters. Determine the velocity of the particle as a function of its position $s$. Evaluate your expression for $s = 5$ m if $k = 0.1 m^{-1}s^{-2}$ and the initial conditions at time $t = 0$ are $s_0 = 3$ m and $v_0 = 10$ m/s.
