Question

17. A ball falling from a building has a kinetic energy of 2000 J and potential

energy of 2376 J. What is the mechanical energy of the ball?
Imc

Answer 1

C. 4736J

Step-by-step explanation:

The mechanical energy of ball is the sum of its kinetic energy and potential energy at any point;

Mechanical energy = kinetic energy + potential energy

Given:

kinetic energy = 2000J

potential energy = 2376J

So;

Mechanical energy = 2000J + 2376J = 4736J
