Answer:
The mechanical energy of the helicopter is .
Explanation:
It is given that,
Mass of the helicopter, m = 3250 kg
Speed of the helicopter, v = 56.9 m/s
Position of the helicopter, h = 185 m
The energy possessed by an object due to its motion is called its kinetic energy. It is given by :
The energy possessed by an object due to its position is called its potential energy. It is given by :
The sum of kinetic and potential energy is called mechanical energy of the system. It is given by :
or
So, the mechanical energy of the helicopter is . Hence, this is the required solution.
The distance from the center of mass is as shown in the image:
<h3>What is the center of mass?</h3>- The center of mass, sometimes referred to as the balancing point in physics, is the only location where the weighted relative position of the distributed mass accumulates to zero.
- Here is where a force can be applied to produce a linear acceleration without also producing an angular acceleration. When calculations in mechanics are made about the center of mass, they are frequently made simpler. It is a fictitious location where one can suppose that an object's full mass is concentrated to see its motion.
- In other words, to apply Newton's equations of motion, the center of mass is the particle equivalent of the provided item.
