The displacement vector of the minute hand on a watch, which measures 2.0 cm in length, can be calculated for two specific time intervals: from 8:00 to 8:20 a.m. and from 8:00 to 9:00 a.m. For the interval from 8:00 to 8:20 a.m., the minute hand moves 120 degrees, resulting in a displacement vector of approximately (1.0, 1.73) cm. In contrast, from 8:00 to 9:00 a.m., the minute hand completes a full 360-degree rotation, yielding a displacement vector of (0, 0) cm.
