Final answer:

The time it takes for the ball to reach its maximum height is 1.6327 seconds, and the maximum height is approximately 12.94 meters.

Step-by-step explanation:

To find the time it takes for the ball to reach its maximum height, we can use the equation for vertical motion:

Final velocity (v) = Initial velocity (u) + (acceleration (a) * time (t))

When the ball reaches its maximum height, its final velocity will be 0 m/s. The initial velocity is 16 m/s (upward) and the acceleration due to gravity is -9.8 m/s² (downward). Plugging in these values, we get:

0 = 16 - 9.8 * t

Solving this equation for time, we find that t = 1.6327 seconds.

To find the maximum height, we can use the equation:

Final velocity^2 = Initial velocity^2 + 2 * acceleration * displacement

At the maximum height, the final velocity is 0 m/s, the initial velocity is 16 m/s, the acceleration is -9.8 m/s², and we want to find the displacement. Plugging in these values, we get:

0 = 16^2 + 2 * -9.8 * displacement

Simplifying, we find that the maximum height is approximately 12.94 meters.
