Maria’s teacher wrote on the board the statement ( as shown^) on the board. she asked him to write a proportion that must be true. Mario wrote (as shown^). do you agree with Mario’s proportion? Justify your answer.

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).
