Question
Please answer parts A & C.
y(t 3T) = A cos(2(32) = Acos(67) = Acos(27) Figure 3 of 3 If the ball is hung on a "stiffer" spring, T will be shorter and the wave will look more compact (meaning the wave peaks will be closer together). On the other hand, if the ball is hung on a "looser" spring, T will be longer and the wave will look more spread out (meaning the wave peaks will be farther apart) y (m) If the ball is lifted higher before being let go, A will be larger, and if it is lifted lower before being let go, A will be smaller. Part A - Indentifying parts of a cosine wave Identify A and T for the cosine function shown in (Figure 3) Express your answer as the amplitude (in m) followed by the period (in s), separated by a comma.

Part A:
A = 3 m and T= 2 s
Part B:
The third graph is right. As A' = 9 m = 3 A and T = 1 s = one half of 2 s
Part C:
