A pendulum of mass 22 kg is released from rest at some height, as shown by
point A in the image below. At the bottom of its arc at point B, it is traveling at
a speed of 13 m/s. What is the approximate amount of energy that has been
lost due to friction and air resistance? (Recall that g = 9.8 m/s2)
A)297j
B)134j
C)45j
D)218j
