    Position and Velocity as a function of time

    1/q=1/f+1/x where x is the ants distance q is the image distance and f is the focal length OR In Newtonian terms: X1 = S1 - f X2 = S2 - f

    Position and Velocity as a function of time

    Homework Statement At time t=0 an ant starts to walk from -2f to -f at a constant speed v. Show that the position (q) and velocity (u) of the ants image as a function of time is given by: q=(2f-vt)f/(f-vt) AND u = f2v/(f-vt)2 Homework Equations d(u/v)/dx = [V(du/dx)-U(dv/dx)]/v2...
