A person rolls a barrel up an inclined plane with a length of 6m and a height of 3m/ How much force is needed to roll up the barrel the length of the inclined plane if the barrel weighs 500N? How much work is done on the barrel?

Respuesta :

Answer:

Length (l) = 6 m

height (h) = 3 m

Load(L) = 500 N

Effort (E) = ?

we know the principal that

E * l = L * h

6 E = 500 * 3

6E = 1500

E = 250

therefore 250 N work is done on the barrel.
