A physical system is called integrable if it has as many conserved quantities as dynamical variables. Consider a body of mass m moving in one dimension x, subject to a conservative force corresponding to potential energy U(x). Hence, the body has conserved total energy E. Construct an integral expression for time on the body's trajectory as a function of position, t(x). Do not attempt to evaluate the integral.
An object weighing 32 lb is released from rest 50 ft above the surface of a calm lake. Before the object reaches the surface of the lake, the air resistance (in lbs) is given by 2v, where v is the velocity (in feet per second).
