A particle of mass m has speed v(x) = α/√x. Calculate the force F(x) responsible. Then, calculate the displacement x(t) of the particle. Homework Equations [/B] The equations that I believe we are supposed to use are f=ma and f=m*dv/dt The Attempt at a Solution [/B] Since F= m*dv/dt, i tried this: F = m*dv/dx*dx/dt = mv*dv/dx = -mvα/(2(x)^(3/2)) And that's as far as I could get for the first problem. However, this seems off because the force is in terms of two variables, right?
