Unformatted text preview: F warms up to 40 F in 3 min while sitting in a room of tem-perature 70 F . Write the diﬀerential equation with all initial data for this problem. Find the formula for the temperature of the beer as a function of time. 7. A swimming pool whose volume is 10 , 000 gal contains water that is 0 . 01% chlorine. Starting at t = 0, city water containing 0 . 001% chlorine is pumped into the pool at a rate 5 gal/min. The pool water ﬂows out at the same rate. Set up the IVP for the unknown x ( t ), the volume of chlorine in the pool at time t . 8. Set up the IVP for the motion of the falling body under the forces of gravity and air resistance, where we assume that the air resistance is proportional to the velocity, in case the initial velocity is directed upward and the initial speed equals p . 1...
