When acceleration is given as a function of displacement, and you are given the velocity and displacement at a particular time, how do you find the time taken for the particular particle to move a certain distance
Can you give a specific example?
When tackling these problems, first use
a=vdv/dx
Integrating both sides with respect to x to give
v2 =f(x)
Taking square root of both sides give
v=g(x)
(Be careful about the sign - use information in the question to
get the correct one). Now, as v=dx/dt, we have
dx/dt=g(x)
Separating variables and integrate, we have
with appropriate limits.
The integral, in general, can only be solved numerically.
Hope this helps.
