A mass on a spring vibrates horizontally on a smooth level surface. Its equation of motion is x(t)=8sint, where t is in seconds and x in centimeter.

a. Find the velocity and acceleration at time t

b. Find the position, velocity, and acceleration of the mass at time t=2pi/3. In what direction is it moving at that time?
