A pendulum is 105cm long and swings about one end through 5 degree on either side of the vertical. One complete swing (i.e. back to the starting point) takes 2 seconds.
(a) Through what angle does the pendulum swing in one complete?
10 degrees
========================
(b) How far does the tip of the pendulum travel in 1 hour?
1 hr = 3600 seconds = 1800 cycles
--> 18000 degrees = 50 revolutions.
Circumference = 2pi*105 cm
travel = 50*2pi*105 cm
10500pi cm = 105pi meters
