To solve the problem of when the two balls meet, we can break it down into a series of steps: ### Step 1: Understand the scenario We have two balls: - Ball 1 is dropped from a height of 100 m (initial velocity = 0). - Ball 2 is thrown upwards from the ground with an initial velocity of 20 m/s. ### Step 2: Set up the equations of motion ...
