As venus revolves around the sun, it travels at a rate of approximately 22 miles per second. convert this rate to kilometers per second. at this rate, how many kilometers will venus travel in 2 seconds? in your computations, assume that 1 mile is equal to 1.6 kilometers. do not round your answers.

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).
