The height, $h$ meters, of a projectile above the ground at time $t$ seconds is given by the function $h(t) = -5t^3 + 30t^2$, where $t \ge 0$. This model is valid for the first 5 seconds of the projectile’s flight.
a. Determine the time(s) when the projectile is momentarily at rest. Explain the significance of each time in the context of the projectile’s motion.
