From the T 2 vs. m graph, determine the period of oscillation if the total mas were 400 g. A 100- g mass oscillates on a spring with spring constant k : 10 N/m. If the amplitude of oscillation is 5 cm, find the position of the mass after 3 seconds. In the above question, a) at what position does the velocity of the mass become maximum? and b) At what time does the velocity of the mass reach its rst maximum?
