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 are at point B, it is traveling at a speed of 13 m/s. What is the approximate amount of energythat has been lost due to friction and air resistance? (Recall that g = 9.8 m/s2)
A. 45 J
B. 218
C. 134J
D. 297 J
