    How Do You Solve an ODE Involving Changing Tank Volume and Concentration?

    I am trying to solve this ODE and am stuck on this step! It is a mass balance of a tank where the volume and concentration are changing by time Fin*Co - Fout*C1 = d(C1*V)/dt Fin*Co - Fout*C1 = d(C1)/dt * V + d(V)/dt * C1 where V = A*h (area and height, where area is constant and height...

    How Do You Solve This Newton's Third Law Problem Involving Friction and Tension?

    Hmm but isn't the force being applied to the whole system which is 3kg? anddd, Fk1 is the kinetic friction acting between block 1 and block 2 and 3.63 is the tension in the rope for block 1. I was guessing all of the forces on block 1 and 2 should be taking into account... I guess not?

    How Far Will a Race Car Travel After Running Out of Gas?

    Hi, well we aren't given the coefficient of friction which makes this question ten times harder -.- Or I could have easily figured this out myself...
