2. Donna's flight from Manchester to Baltimore was at an average speed of 375 mph.   Is this a scalar quantity, a vector quantity or neither?

  scalar

  neither

3. Vector V has a magnitude of 921 and is approximately 21^o west of south.  Express this vector in polar form. 

  V = 921 21^o

  V = 921 249^o

  V = 921 201^o

4. Vector V has a magnitude of 921 and is approximately 21^o north of east.  Express this vector in rectangular form.

  V = (860, 330)

  V = (859.8, 330.1)

  V = (-504, 770)
