Nadia's community group is raising money for kids in developing
countries. They plan to have a marathon Scrabble game. They
have constructed a 2 m by 2 m playing boardThe letter tiles are 2
cm by 2 cm. How many squares will there be on the board?

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).
