can any1 help me solve this? d2x/dt2 = -(k/m)*x -g
at x= 0, t=0, v=sqrt(u^2-2gh)
what is x?? can show the steps?

A second order differential equation is a mathematical equation that involves the second derivative of a function. It is commonly used to describe physical phenomena in areas such as mechanics, electricity, and heat transfer.
To solve a second order differential equation, you can use various methods such as separation of variables, variation of parameters, or the method of undetermined coefficients. These methods involve finding a general solution that satisfies the equation, and then using initial conditions to find a particular solution.
Initial conditions refer to the specific values of the function and its derivatives at a given point. These values are used to determine the particular solution of a differential equation, as they help to narrow down the possible solutions to a specific one.
A homogeneous second order differential equation has a zero on the right-hand side of the equation, meaning it can be written in the form of y'' + p(x)y' + q(x)y = 0. On the other hand, a non-homogeneous second order differential equation has a non-zero term on the right-hand side and can be written as y'' + p(x)y' + q(x)y = f(x).
Second order differential equations are commonly used to model various physical phenomena such as the motion of a pendulum, the motion of a spring, and electrical circuits. They are also used in fields like economics, population dynamics, and engineering to make predictions and solve problems.
