part 2 of 2
find the y-coordinate of the
ity (as a multiple of a).
answer in units of a.

(,)

Step-by-step explanation:

Given data,

Side of square = a

center of gravity of x,y

=

=

now, find the center of mass of each plate

For plate 1

W = 10N

x- coordinate = a/2

y- coordinate = a+a/2 = 3a/2

For plate 2

W = 30N

x- coordinate = a+a/2=3a/2

y- coordinate = a+a/2 = 3a/2

For plate 3

W = 70N

x- coordinate = a+a/2=3a/2

y- coordinate = a/2

For plate 4

W = 60N

x- coordinate = a/2

y- coordinate = a/2

= = =

= = =

Therefor (,) will the center of  gravity

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !
