The total cost, c, of bananas is proportional to the number of pounds, p, purchased. Bananas are selling for 79 cents per pound this week. Which equation represents the cost for the total number of po. unds purchased?

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
