At the top of a giant swing on the gymnastics high bar, candy's velocity is 1 m/s, and she is 3.5 m high. if candy's mass is 50
Allushta [10]
The total mechanical energy is the sum of the kinetic energy and the gravitational potential energy:
E=K+U= \frac{1}{2}mv^2 +mgh
where m=3.5 kg is Candy's mass, v=1 m/s is her velocity and h=3.5 m is her height. If we replace these numbers, we find the mechanical energy of the system:
E= \frac{1}{2} (50 kg)(1m/s)^2 + (50 kg)(9.81 m/s^2)(3.5 m)=1742 J =1.74 kJ

Grace [21]

Answer:

Energy: Kinetic, Sound, Thermal, gravitational, electric, light and nuclear

Explanation:

This exercise asks to clarify a little some important concepts

* Energy. It is the capable one that has the bodies to carry out a job.

* Kinetic energy. It is the energy due to the movement of objects

* sound energy. It is the energy due to the vibration of the atoms or molecules of the materials, it can be solid, liquid or gaseous

* Thermal energy. It is the energy due to movement of the particles

* Gravitational Energy. It is a configuration energy due to the height of the bodies with respect to a reference point

* Electric power. It is due to the movement of electric charges

* light energy. It is the energy that light carries due to the electric and magnetic fields that form it, it occurs throughout the electromagnetic spectrum

* Nuclear energy. It is the energy stored in the nucleus by the configuration and movement of protons and neutrons.
