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?

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.

they start with the same

i think the answer is a and b

i wish you luck
