If an object has 50 Joules of kinetic energy and 237 joules of potential energy, how much mechanical energy does it have? ME = PE + KE

Respuesta :

Answer:

287J

Explanation:

Given parameters:

Kinetic energy = 50J

Potential energy = 237J

Unknown:

Mechanical energy  = ?

Solution:

The mechanical energy of a system is the sum of the potential energy and kinetic energy of that system.

  Kinetic energy  = Potential energy + Kinetic energy

  Kinetic energy  = 50J + 237J  = 287J
