The force f on an object is the product of the mass m and the acceleration a. in this problem, assume that the mass and acceleration both depend on time t, hence so the does the force. that is, f(t)=m(t)a(t) at time t=7 seconds, the mass of an object is 49 grams and changing at a rate of −1gs. at this same time, the acceleration is 11ms2 and changing at a rate of −10ms3. by the product rule, the force on the object is changing at the rate of .
