Find an expression for the time variation of the kinetic energy T as a function of the angular velocity vector ω and the total torque vector τ acting on the body.. In effect, find

(b) Newton’s second law may be written as ˙ p = f (r)r/r for a general central force. Use this equation on the position vector r to an object with mass m in order to derive
