For u = 〈1,5〉 and v = 〈3, −2〉 as in problem 2, part (a), what is the magnitude of u + v?

5

Step-by-step explanation:

Data provided in the question:

u = 〈 1 , 5 〉

and v = 〈 3, −2 〉

or it can also be represented as:

u = 1i + 5j

and,

v = 3i - 2j

now,

u + v = ( 1i + 5j ) + ( 3i - 2j )

or

u + v = 4i + 3j

Now, the magnitude is given as:

=

thus,

magnitude of ( u + v ) =  

or

=

or

= √25

= 5
