Question

A vector d has a magnitude 7.7 m and is directed south. What are (a) the magnitude and (b) the direction of the vector 7.2? What are (c) the magnitude and (d) the direction of the vector -6.1?

Answer 1

Our values are,

`d=7.7m`

`d= \downarrow`

A) As the symbol not change both have the same direction, so

Magnitud is,

`c= 7.7*7.2 = 55.44m`

b) As the symbol change the direction of vector '6.1' is
`\uparrow`

The magnitud will be
`= 6.1*7.7 = 46.97m`
