I'm completely lost on this question:
[h=1]In physics, the kinetic energy of a moving object is given by the formula K=1/2mv^2 where m is the mass of the object and v is the object's velocity.Suppose a rocket is increasing in velocity at 10m/sec^2, and is decreasing in mass at 15kg/sec because it is using up fuel. How fast is it's total kinetic energy changing when the velocity is 30m/sec and the mass is 1000kg? Round to the nearest tenth.[/h]I know we have to find the derivative of the kinetic energy equation. and somehow plug dv/dt and dm/dt
