Which statement best describes the PE-KE transformations for a javelin, starting from the instant the javelin leaves the thrower's hand until it hits the ground.

point ich statement best describes the PE-KE transformations for a javelin, starting from the instant the javelin leaves the thrower's hand until it hits the ground. Initial PE is transformed to KE until the javelin reaches the high point of its arc. On the way back down, KE is transformed into PE. At every point in the flight, mechanical energy is being transformed into heat energy. Initial KE is transformed to PE until the javelin reaches the high point of its arc. On the way back down, there is no transformation of mechanical energy At every point in the flight, mechanical energy is being transformed into heat energy. Initial PE is transformed to KE until the javelin reaches the high point of its arc. On the way back down there is no transformation of mechanical energy At every point in the flight, mechanical energy is being transformed into heat energy. Initial KE is transformed to PE until the javelin reaches the high point of its arc. On the way back down, PE is transformed into KE.
