Problem 15 34- Enhanced-with Feedback Part A In a science museum, a 100 kg brass pendulum bob swings at he and of a 123 m long wre. The pandulum& started at eoxactly 8:00 am every Ad asacty 12 00 noon, how many oscilatons wil the pendukum have completed? Express your answer as an integer moming by puilkng t 16 mto ta side and seleasing it Berause of ts ompact shape and smooth surface, the pandulum's damping constant is only 0,010 kg.s You may want to revew (L03201 409 41 My Answers Sitee Part B Express your answer to two significant igures and Include the appropriate units

Explanation / Answer

a] time period = 2pi* sqrt(l/g) = 2pi*sqrt(12.3/9.8) = 7.039136 s

number of oscillations = (4*60*60)/7.039136

= 2046 answer

b] A = A0* e^(-gamma t)

= 1.6*e^((-0.010/(2*100))*(4*60*60))

= 0.7788 m answer
