Best ResponseYou've already chosen the best response.1This question should have been asked in the physics sections but I'll still provide you an answer. Work done (Joules) = Force (N) x Distance (m) The only force that we know of that is acting on the toy (ignoring resistive forces) is the weight and tension of the string lifting the object. Weight = mass x acceleration due to gravity = mg. The tension is the force that is causing the work to be done and is equal to the weight. So tension = mg. Work Done = Tension x distance. = 1.5 x 9.8 x 1.2 dw:1354221984926:dw
