Physics
A mass travels in a straight line on a horizontal plane. It is attached at one end to a fixed vertical wall through a spring (spring constant ) while at the other end, it is connected through an inextensible cable to a pendulum of mass m. The lower mass m will oscillate in the vertical plane ABC and there is no friction. Using the position x of the mass and the angle theta of the mass m, as the configuration variables, write the two equations of motion.

The equations are as below:
Explanation:
As the complete question is not given, the complete question is attached herewith.
From the given data
The mass of the block is M
The length of the spring at any given time is l
The length of the spring initially is lo
The length of the platform is lr
So the coordinates in y and z direction are given as
Now the Lagrange is given as
Now The value is given as
So the 1st equation becomes
Now the second equation is as
Ответ:
They would create an ionic compound because lithium is a metal and fluorine is a nonmetal.
Metal + Nonmetal = binary ionic compound.
