Question

A 0.100-kilogram apple falls from a height of 1.50 meters to 1.00 meter. Ignoring frictional effects, the total mechanical energy of the apple at this height is _____.

0.00 J
less than 1.47 J but more than 0.00 J
exactly 1.47 J
more than 1.47 J

Answer 1

Mechanical energy consists of potential energy and kinetic energy.

Potential Energy:
\[PE = m \times g \times h\]

Kinetic Energy:
\[KE = \frac{ 1 }{ 2 }mv^2\]

Where,
m = mass
g = gravity
h = height
v = velocity

Answer 2

So, what's the answer?

Answer 3

Use conservation of energy principles to solve the problem

Answer 4

more than 1.47 J?

Answer 5
