To solve the problem step by step, we will first calculate the velocity of the ball after 1 second and then calculate the displacement. ### Step 1: Calculate the final velocity after 1 second 1. **Identify the given values:** - Initial velocity (u) = 12 m/s (upward) - Acceleration (a) = -g = -9.8 m/s² (downward, due to gravity) - Time (t) = 1 s ...
