34 An aluminum pie pan is attached to a string and suspended from a hook, as shown in the diagram below. The pan is released from position A and swings through the air to position B. Aluminum pie pan. What is the relationship between the kinetic energy at position B, KEB, and the gravitational potential energy at position A, PE, with respect to B? (1) KE, is equal to PE, minus work done against friction. (2) KE is equal to the PEA plus work done against friction. (3) KE, is equal to PEA- (4) KEg is equal to 2PEA.
