Consider the motion of the tip of the minute hand of a clock. In one hour, the displacement and average velocity is .......
Displacement is the straight-line distance from the starting point to the end point. The minute hand returns to the starting point in one hour. Therefore the displacement is zero.
V = d/t = 360o/h = 2pirad/h = 6.28 rad/h.
To determine the displacement and average velocity of the tip of the minute hand of a clock in one hour, we need to consider the distance covered and the direction of the motion.
The minute hand of a clock rotates 360 degrees in 60 minutes, or 6 degrees per minute. In one hour, it completes a full circle, which is 360 degrees.
The displacement of an object is the straight-line distance between its initial and final positions, regardless of the path taken. In the case of the minute hand, its initial and final positions coincide at the starting point, the 12 o'clock position. Therefore, the displacement of the tip of the minute hand in one hour is zero.
Average velocity is defined as the total displacement divided by the total time taken. Since the displacement is zero, the average velocity of the tip of the minute hand in one hour is also zero.
Therefore, in one hour, the displacement and average velocity of the tip of the minute hand of a clock are both zero.
