Answer:
Verified that he oscillations are exactly isosynchronous with frequency ω0 = p g/l, independent of the amplitude.
Explanation:
Starting from the first principle for the derivation and to prove that the oscillations are exactly isosynchronous with frequency ω0 = p g/l, independent of the amplitude. The mathematical manipulations was applied, trigonometric identities was also applied.The steps and explanation are shown in the attachment.

Answer:
The total work done by Brad each day is 176400 J
Explanation:
Hi there! The work done by a force (F) pointed in the same direction as the displacement (d) is calculated as follows:
W = F · d
The force applied is equal to the weight of Brad, that is calculated as follows:
Weight = m · g
Where:
m = mass of Brad
g = acceleration due to gravity (9.8 m/s²)
Then:
Weight = 60 kg · 9.8 m/s² = 588 N
Let´s find the vertical distance traveled by Brad each day:
He exercises 20 min per day. Each minute Brad does 60 steps. In total, Brad steps up (20 min · 60 steps/min) 1200 steps. If each step has a height of 0.25 m, the total distance traveled by Brad will be
(1200 steps · 0.25 m/step) 300 m.
Then, the total work done by Brad is
W = F · d
W = 588 N · 300 m
W = 176400 J
The total work done by Brad each day is 176400 J
