A wall clock has a minute hand with a length of 0.47 m and an hourhand with a length of 0.26 m. Take the center of the clock as theorigin, and use a Cartesian coordinate system with the positive xaxis pointing to 3 o'clock and the positive y axis pointing to 12o'clock. Express the position vectors of the tip of the hour hand() and the tip of the minute hand () at the followingtimes.(determine whether it is positive or negative x , positive ornegative y in each vector
(a) 12:00
=A ( m)

=B ( m)

(b) 3:00
= A( m)

=B ( m)

(c) 6:00
=A ( m)

=B ( m)

(d) 9:00
=A ( m)

=B ( m)

The minute hand of a wall clock measures 18 cm from its tip to theaxis about which it rotates. The magnitude and angle of thedisplacement vector of the tip are to be determined for three timeintervals. What are the (a) magnitude and (b) angle from a quarterafter the hour to half past, the (c) magnitude and (d) angle forthe next half hour, and the (e) magnitude and (f) angle for thehour after that? Give all angles as positive values measuredcounterclockwise from the +x direction (to the right, or 3o'clock).
