Consider the motion of the tip of the minute hand of a clock. Over the course of one hour,

Step-by-step solution

Over the course of one hour, the minute hand of a clock completes exactly one full revolution. The initial and final positions of the tip of the minute hand are identical, meaning the shortest distance between them is zero. Therefore, the displacement is zero. Average velocity is defined as the ratio of displacement to total time taken. Since the displacement is zero, the average velocity is also zero. The distance covered by the tip is the circumference of the circular path, 2 R , which is non-zero. Consequently,
