Question

A 2 kg plant vase is on a 1.6m high table. If, g = 10m / s², determine the potential gravitational energy of the plant vase in relation to the ground.

Answer 1

Resposta:

32 J

Explicação:

The gravitational potential energy can be written as

U = m.g.h

where

m = mass

g = acceleration due gravity

h = height

We have

m = 2 kg

h = 1.6 m

g = 10 m/s²

hence

U = 2 x 10 x 1.6

U = 32 J    (answer)
