An object of mass m, which is confined to move on the "x-axis", is
subject to a resoring force F. You know that the magnitude of F is
proportional to xn3, where
x is the position on the x-axis. You want to determine the exponent
n3, so you carry out two experiments. You bring the
object out to the position x=d and release it from rest, it returns to the origin (x=0)
where you measure it's speed to be v0. Now you bring the object out to
the position x=n1d and release it from rest. You measure it's speed v
as it passes though the origin at x=0 and obtain v=n2v0.
With this information, determine the exponent n3? Note that
n1, n2 and n3 are unitless.
