The graph shows the position of an object in simple harmonic motion as a function of time. What are the first two times after zero at which the object is moving with its maximum speed? t(s) = What is the object's maximum speed? Max speed (m/s) = x (m) 0.6 0.3 -0.3- -0.6- 0.7 1.4 2,1 2.8 t (s) 3.5 4.2 N
