in un negozio di arredamento, un addetto preleva da uno scaffale alto 1,95m un pacco di coperte e lo deposita a terra, spostandolo a velocita costante e compiendo un lavoro di -197j. Qual'è la massa del pacco? Il secondo addetto compie la stessa operazione, ma durante la discesa il pacco ha un'accelerazione verso il basso di 0,20m/s/2. Quanto lavoro compie il secondo addetto?(non considerare le fasi iniziali e finali del moto del pacco)
