The mechanical energy of an object is equivalent to the sum of its potential and kinetic energy. If the helicopter is grounded, then its mechanical energy will be 20 J. If it is in the air, then its potential energy will be calculated using:P.E = mghAnd then added to the kinetic energy to obtain mechanical energy.

Energy per time is called the power. It is the rate of energy. For this question, we simply divide the values. We do as follows:

Mechanical energy per time = 20 J / 2.5 s = 8 J /s

Is it easier or more difficult to stage a protest at school?

RoseWind [281]

Answer:

c. They are the same

Explanation:

I would say they are the same. It may be more difficult because if you start a protest, people might not support you because they don't want to get in trouble. If it was easier, you might have those types of schools where you start a protest and the big and bold people don't care what happens to them, which would help you with the protest. It actually all depends on who would actually want to help you whether they are your friends or not. It basically depends on what caused the protest.

Hope this helped!!!
