+127 How much work is needed to lift an object that weighs 150 N to a height of 5 m? How much Gravitational potential energy did the object gain when the work was done on it?
(5star rating if you anser it correctly)
+15068 Hello mayazhanmath!
How much work is needed to lift an object that weighs 150 N to a height of 5 m?
The work done is 150N×5m.
W=F×s=150N×5m=750 Nm or 750 Ws.
The gravitational potential energy
grows around this size.
