The positions of two masses, ma and mb, are described by the equations: a(t) = 3A sin (4wt) and x(t) = 2A sin (3wt). (a) Not including t = 0, what are the first three times that the masses will pass through their respective equilibrium positions simultaneously? (b) Find the two expressions that would describe each mass' velocity. What were the velocities at the times you found in part a?
