Question

ANSWER FAST PLEASE
Maria’s class has learned how to drop an egg without breaking it. After 0.2 s, the kinetic energy of the falling egg is 0.5 J. If its mechanical energy is 2.3 J, what is its potential energy?

A. 1.2 J
B. 1.8 J
C. 2.8 J
D. 4.6 J

Answer 1

2.8 J

this is a right answer helpful

Answer 2

The Potential energy of the body is 11.8 Joules

The mechanical energy of the egg is given by the formula:

Mechanical energy = Potential energy + kinetic energy

Given the following parameters;

• Mechanical energy = 2.3 Joules
• Kinetic energy = 0.5 Joules

From the formula:

Potential energy = ME = KE

Potential energy = 2.3 - 05

Potential energy = 1.8 Joues

Hence the potential energy of the body is 11.8 Joules
