Question

A 12 kg mass is lifted to a height of 2 m. What is its potential energy
at this position?

Answer 1

PE = 23.8 J

Step-by-step explanation:

It's known through the International System that the gravity of the earth is 9.8 m/s², so we have as...

Data:

• m = 12 kg
• g = 9.8 m/s²
• h = 2 m
• PE = ?

Use formula:

• 
  `\boxed{\bold{PE=m*g*h}}`

Replace and solve:

• 
  `\boxed{\bold{PE=12\ kg*9.8(m)/(s^(2))*2\ m}}`

• 
  `\boxed{\boxed{\bold{PE=23.8\ J}}}`

The potencial energy is 23.8 Joules.
