Question

An object with a kinetic energy of 200 J and Potential energy of 300 J, has a mechanical energy of what?

Answer 1

500 J

Step-by-step explanation:

Emechanical=U+K,i.e., the mechanical energy Emechanical is the sum of the potential energy U and kinetic energy K.

So, the object has a mechanical energy of 200+300=500 J.
