Question

Andrew lifts a table 7 meters from the ground floor of her house to his attic. If the

table weighed 20 kg, what is the gravitational potential energy gained by the table?
Estimate g as 9.81.
1300
O 1400
1500 J
1600J
1700

Answer 1

1372 J

Explanation:

Gravitational potential energy = m×g×h

m = mass of the object

g = gravitational acceleration

h = elevation

E = 20×9.8×7

= 1372 J
