Multiple choice

An object’s kinetic energy is 50J and the energy is 120J, its total mechanical energy is?

  1. 70 J

  2. 170 J

  3. 2.4 J

  4. 6000 J

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Total mechanical energy is the sum of kinetic energy and potential energy. Given 50J kinetic and 120J potential, the total is 50 + 120 = 170J.
