Answer : The mechanical energy of the rock is, 134 J
Solution :
As we know that the mechanical energy is equal to the sum of the kinetic energy and the potential energy.
The formula used for mechanical energy is,
where,
M.E = mechanical energy
K.E = kinetic energy
P.E = potential energy
m = mass of an object = 2 Kg
v = velocity of an object = 6 m/s
h = height = 5 m
g = acceleration due to gravity = 
Now put all the given values in the above formula, we get the mechanical energy of the rock.
![M.E=[\frac{1}{2}(2Kg)\times (6m/s)^2]+(2Kg\times 9.8m/s^2\times 5m)=134\text{ Kg }m^2s^{-2}=134J](https://tex.z-dn.net/?f=M.E%3D%5B%5Cfrac%7B1%7D%7B2%7D%282Kg%29%5Ctimes%20%286m%2Fs%29%5E2%5D%2B%282Kg%5Ctimes%209.8m%2Fs%5E2%5Ctimes%205m%29%3D134%5Ctext%7B%20Kg%20%7Dm%5E2s%5E%7B-2%7D%3D134J)
Therefore, the mechanical energy of the rock is, 134 J
Answer:
undefined status
Explanation:
Adolescence stage of life is generally regarded as the period of life between the normal onset of puberty and the beginning of early adulthood. The stage of puberty is characterized by appearance of secondary sexual characteristics as well as the development of reproductive features.
Adolescent often have vague or unclear expectations as a result of the fact that many adults still regard adolescents as children even though some other adults may regard them as fellow adults.
This undefined status makes adolescents not to exactly know what to expect as their roles or rights in the society.
You could do something about Einstein's theory of energy... it seems like it would be a simple and easy project. E=mc^2
Answer:
<h2>18150 J</h2>

We have the final answer as
<h3>18150 J</h3>
Hope this helps you
Explanation:
The SI unit of power is the kilogram-meter2 per second cubed, which is called the watt (1 W = 1 kg-m2/s3). Since power is the energy used per unit of time, it is derived as the energy/time quotient.
Kelvin is a fundamental unit! It's a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity. Time is said to be a fundamental unit because it is not dependent on one or more units
