To solve the question, we need to analyze the motion of the boy on the merry-go-round. Here’s a step-by-step breakdown of the solution: ### Step 1: Understand the Motion The boy is riding on a merry-go-round that is moving with a constant speed of 10 m/s. **Hint:** Consider the difference between speed and velocity. Speed is a scalar quantity, while velocity is a vector quantity that includes direction. ### Step 2: Identify the Type of Motion ...
