Rick Scott and Kim are pushing a box. Scott is pushing directly west with a speed of 15 ft/min. Rick is pushing 30 degrees south of west with a speed of 12 ft/min. Kim is pushing directly northwest with a speed of 14 ft/min.

Write a velocity vector that describes the net movement of the box.

Solution

scott is pushing directly west with a speed of 15ft/min . rick is pushing 30 degree south of west witha speed of 12ft/min . kim is pushing directly northwest at a speed of 14ft/min . velocity vector that describe the net movement of the box =xi+yj+zk v=15i+12j+14k.
