SUMMARY

The discussion focuses on deriving the velocity function v(t) from the force function F(x) = sqrt(x) * sin(x^2) for a 1 kg block on a frictionless surface. The key equation utilized is a rearrangement of Newton's second law, expressed as a = dv/dt = (dv/dx) * (dx/dt) = v * (dv/dx). The general procedure involves applying the chain rule in kinematics and understanding velocity-dependent forces. The reference provided offers additional insights into the derivation process.

TL;DR
Derive v(t) from F(x) = sqrt(x) * sin(x^2) for 1 kg block on level surface (or from F(x) in general if that function is too difficult)
Assuming I push a 1 kg block on a level surface, with no energy lost to friction, and I have an equation F(x) for force in terms of position, how would I derive an equation v(t) for velocity in terms of t? Specifically the function F(x) = sqrt(x) * sin(x^2), for 0 <= x <= sqrt(pi), if possible, but also just looking for the general procedure for any F(x).
