We can represent the problem as shown in the attached drawing
L1=x1
L2=x2
L=x------------distance of the center of mass
we have that
L1/L2=m2/m1------------------> L1*m1=L2*m2------------->m2=L1*m1/L2
moment = Md
the moment about O is defined to be
m1*L1+m2*L2=(m1+m2)*L
L=(m1*L1+m2*L2)/(m1+m2)
m1*L1+m2*L2=2*m1*L1--------remember-------------------->L1*m1=L2*m2
L=(2*m1*L1)/(m1+L1*m1/L2)
L=(2*m1*L1)/(m1*L2+L1*m1)/L2=(2*m1*L1)*L2/(L2*m1+L1*m1)
L=(2*L1*L2)/(L1+L2)
the coordinates of the center of mass are (L,0)
Answer:
k=0
Step-by-step explanation:
R(x)=kx-2x²
R(1/4)=k(1/4)-2(1/4)²=k/4-1/8
R(-1/4)=k(-1/4)-2(-1/4)²=-k/4-1/8
R(1/4)=R(-1/4)
k/4-1/8=-k/4-1/8
k/4+k/4=1/8-1/8
2k/4=0
2k=0
k=0
Answer:
x=-11/8
Step-by-step explanation:
x-(5/8)=-2
Give the -2 a common denominator to make it easy
x-(5/8)= -16/8
Add the 5/8 to the -16/8
x= -11/8
