Problem

A skier moves with a speed of

14\,\text{m/s}

in a direction

30^\circ

above the line of greatest slope. The line of greatest slope itself is oriented

15^\circ

below the horizontal

+x

direction. Determine the skier’s velocity components along the horizontal

x

axis and the vertical

y

axis. Use

+y

as upward.
