Stone Weight matters

Since The work done is done on the stone

Mass=20kg

Height = 30m

Work Done = Force x Displacement

Force To lift the stone will be

F= mass x Acceleration(g)

F= 20 x 10

F= 200N

Work done = 200 x 30

$\implies$$\large{\boxed{\boxed{6000J}}}$

Answer 2

Answer:

24 kj

Explanation:

work = mgh = 800x30 = 24 kj
