Question

Sasha lifts a couch 8.2 meters from the ground floor of her house to the attic. If the couch has a mass of 120 kg, what is the gravitational potential energy gained by the couch? Estimate g as 9.81 m/s^2.

Answer 1

9653.04 joules

Step-by-step explanation:

H= 8.2 m

M= 120 kg

G= 9.81 m/s^2

P.E= ?

P.E = MGH

P.E = 120 x 9.81 x 8.2

P.E = 9653.04 joules
