A wall clock has a minute hand with a length of 0.46 m and an hour hand with a length of 0.26 m. Take the center of the
clock as the origin, and use a Cartesian coordinate system with the positive x axis pointing to 3 o'clock and the positive y
axis pointing to 12 o'clock. Find the displacements of the tip of each hand (that is, AÁ and AB) when the time advances
from 3:00 P.M. to 6:00 P.M. (Á and B represent the tip of the hour hand and the tip of the minute hand, respectively.)
AA =
AB =
The minute hand on a watch is 1.00 cm in length. Assume the origin of the xy-plane is at the center of the clock face, the x-axis points in the same direction as the minute hand at 8:15 a.m., and the y-axis points in the same direction as the minute hand at 8:00 a.m.
What is the displacement vector of the tip of the minute hand from 8:00 to 8:20 a.m.?
Enter the x and y components of the displacement vector in centimeters separated by a comma.
What is the displacement vector of the tip of the minute hand from 8:00 to 9:00 a.m.?
Enter the x and y components of the displacement vector in centimeters separated by a comma.
