Answer: The angle through which the pendulum travels = .
Step-by-step explanation:
Formula: Length of arc: , where r= radius ( in radians) ,
= central angle.
Given: Length of pendulum (radius) = 45 cm
Length of arc= 27.5 cm
Put these values in the formula, we get
In degrees ,
Hence, the angle through which the pendulum travels = .
