Vectors Quiz: Part I

You and your friends are navigating through a corn maze. Your path is described by the displacement vectors:

(0, 50) m (70, 0) m (0, -30) m (-60, 0) m (0, 10) m

What is your resultant displacement?

• a) (30, 10) m

• b) (40, 0) m

• c) (10, 30) m

• d) (40, 40) m

Convert the velocity vector v → =(6.0, 8.0)  m/s   into polar coordinates.

• v → = 10 m/s at 0.64°

• v → =  10 m/s at 53°

• v → = 5.3 m/s at 53°

• v → = 3.7 m/s at 27°
