Answer:
Explanation:
A stretching routine should target most of the main muscles in the body and at least one stretching exercise per section of the body. Also in a work environment since individual's sizes, ages, and cultures vary you should design a routine that is for beginners and very easy and effective. Regardless, each individual should be able to move at their own pace and push as far as they are physically able. One such routine would be the one in the attached picture below which targets all major areas, is easy and effective. It starts at the neck muscles and works its way down the arms, back, and legs.
The new rotational energy of the system(RE) =
How this is calculated?
- Distance of each astronaut from centre of mass(m)=d/2
- Moment of inertia of system
- Speed of astronauts=v
- So, angular speed,ω =
=
- Rotational energy of system=
where, ω= angular speed
What is rotational energy?
- Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy.
- Looking at rotational energy separately around an object's axis of rotation, the following dependence on the object's moment of inertia is observed
