Two stores each have the same number of lawn mower for sale. The lawn mower at store A have a median price of 150.The lawn mowers at Store B have a median price of 200.What can be inferred about the data?

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).
