What is the potential energy of a rock that weighs 5 kg and sits on top of a 10- meter high hill?.

Respuesta :

Answer:

490 Joule

Explanation:

Solution:

Given,

  • Mass (m) = 5 kg
  • Acceleration due to gravity= 9.8 m/s
  • Height (h)= 10 m

Here,

Potential Energy (P.E.)= mgh

=5×9.8×10

= 490 Joule
