Question

How much gravitational potential energy does a 7.3 kg rock have if it is sitting on the edge of a cliff that is 12 m high?

Answer 1

8.7 sorry if wrong

Step-by-step explanation:

Answer 2

The given data provided in the question is as follows:

• Mass (m) = 7.3 kg

• Height (h) = 12 m

• Gravitational acceleration (g) = 9.8m/s²

We have given to find out the gravitational potential energy produced i.e

• Gravitational potential energy (GPE) = ?

The standard formula for calculating GPE is given by,

`\mapsto\tt{m * g * h}`

`\mapsto\tt{7.3 * 9.8 * 12}`

`\mapsto\tt{71.54 * 12}`

`\mapsto\tt{858.48}`

• Thus, the value of gravitational potential energy is 858.48 J
