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

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

which are post-impressionist paintings? check all that apply?

explanation:

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and color.

hope this have a good day
