The total time for the ball to return to its starting point can be found using the formula $t = \frac{2v}{g}$, where $v$ is the initial velocity (36 m/s) and $g$ is the acceleration due to gravity (approximately 9.8 m/s$^2$). Plugging in the values, $t = \frac{2 \times 36}{9.8} \approx 7.3$ seconds.
