Bordery conditions: x(t=0) = L, x(t=T)= 0.

Given magnetic force F(x) = kx(t)^-2, here k is constant.

If uncontrolled, there is big crash noise afer solenoid actuated, so I wish it pull plunger at constant power.

Help me find the dynamic position x(t), then I can get velocity.

I know Wolfram software may resolve it, but I have no money to buy it.
