To solve the problem of finding the relative speed of two balls, A and B, we will follow these steps: ### Step 1: Understand the motion of each ball - Ball A is dropped from a height of 45 m. Its initial velocity (u_A) is 0 m/s. - Ball B is thrown upwards with an initial velocity (u_B) of 40 m/s. ### Step 2: Write the equations of motion For ball A (dropped): ...
