    Finding the initial velocity of a projectile so that it hits a moving object

    I uh... don't know. I'm new here. Don't know who could do that.

    Classical Dynamics: Given v(x), find F(x), x(t), and F(t).

    Although, I can't seem to find x(t). Running into the same wargarbl.

    Classical Dynamics: Given v(x), find F(x), x(t), and F(t).

    BAH! I swear I tried that method and got a bunch of warrgarrbllll. Thanks. I can't believe I messed it up that bad.

    Classical Dynamics: Given v(x), find F(x), x(t), and F(t).

    Homework Statement The speed of a particle of mass m varies with the distance x as v(x) = (alpha)*x-n. Assume v(x=0) = 0 at t = 0. (a) Find the force F(x) responsible. (b) Determine x(t) and (c) F(t)Homework Equations Likely: F = maThe Attempt at a Solution I obtain a(x) = -n(alpha)x-(n+1) So...
