Question

two poin masses of mass 1 kg and 2 kg are lying at point a (2,0) and b (-1,0) m respectively the coordinatr of centar mass is​

Answer 1

Answer:

Let the coordinates of mass mass be (x,y)

x=(

m1x1+m2x2

m1+m2

 

=

1×(-1)+2×3

3

 

=

-1+4

3

 

=1

y=

m1y1+m2y2

m1+m2

 

=

1×2+2×4

3

 

=

2+8

3

 

=

10

3

 

Therefore, the coordinates of center of mass be (1,10/3)`

Answer 2

Step-by-step explanation:

Given two point masses of mass 1 kg and 2 kg are lying at point a (2,0) and b (-1,0) m respectively the coordinate of centre mass is

• So the masses of two points are given.
• So m1 = 1 kg
•     m2 = 2 kg
• So the coordinates are (2,0) and (-1,0)
• So x1 = 2, y1 = 0
•     x2 = -1, y2 = 0
• We need to find the coordinates of centre of mass. (X,Y).We have
•   X = m1x1 + m2x2 / m1 + m2
•       = 1(2) + 2(-1) / 1 + 2
•      = 2 – 2 / 3
•      = 0
•  Y = m1y1 + m2y2 / m1 + m2
•      = 1(0) + 2(0) / 1 + 2
•      = 0 + 0 / 3
•      = 0
• Centre of mass coordinate will be (X,Y) = (0,0)
