Determine the mechanical energy of the subject: a 1 kg pendulum has a speed of 2 m/s at a height of 1 m
a) 9.8j
b) 11.8j
c)2j
d7.8j

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

total distance/total time

(85 + 82)/(5+3)

167/8
