AI Generated Solution

To calculate the velocity of the ball when it reaches the ground, we will use the equations of motion. Here's a step-by-step solution: ### Step 1: Identify the known values - Initial velocity (u) = 19.6 m/s (upward) - Acceleration (a) = -g = -9.8 m/s² (since gravity acts downward) - Time (t) = 5 s ### Step 2: Use the equation of motion ...
