    Ordinary Differential Equation - tank with inflow and outflo

    1. Homework Statement A tank contains 60 kg of salt and 2000 L of water. A solution of a concentration 0.015 kg of salt per liter enters a tank at the rate 6 L/min. The solution is mixed and drains from the tank at the same rate. Find the amount of salt in kg at t = 3 hours Find the...

    Finding Power when no time or velocity are provided?

    I would have used it this way: We know that the potential energy is 0 at the beginning and that at the end of the motion it is 9188 joules. Therefore, by using the law of conservation of energy I would equal the initial kinetic energy to the final potential energy like this -> KEo = PEf ->...

    Finding Power when no time or velocity are provided?

    Ok but would it make sense to use the law of conservation of energy?

    Finding Power when no time or velocity are provided?

    1. Homework Statement A man weighing 125kg walks 15m up to the top of a plane inclined at 30 degree to the horizontal. find A) Work he has done B) the increase in Potential Energy C) If he wants to go to the top of the plane, what is his horsepower? 2. Homework Equations PEo + KEo = PEf +...
