Engineers must understand the thermal properties of materials to be able
to predict the performance of any given material over its lifetime in a
specific application. Engineers apply their understanding of the
thermal properties of materials to the design of efficient heat transfer
materials for better engines, spacecraft and electronic devices. They
also examine the thermal properties of insulation to design more
efficient buildings and homes. Engineers develop ways to minimize heat
transfer from a motor to the surrounding environment. Often they find
ways to insulate the motor to decrease the convective heat transfer from
the motor. They design a refrigerator to keep heat out of the inside,
as well as keep the refrigerator contents cool. hope this helped
Answer:
Examples for Rectilinear Motion
1) The use of elevators in public places is an example of rectilinear motion.
2) Gravitational forces acting on objects resulting in free fall is an example of rectilinear motion.
3) Kids sliding down from a slide is a rectilinear motion.
4) The motion of planes in the sky is a rectilinear motion.

Well, st first we should find <span>initial momentum for the first person represented in the task which definitely must be :
</span>
And then we find the final one :
Then equate them together :
So we can get the velocity, which is
In that way, according to the main rules of <span>conservation of momentum you can easily find the solution for the second person.
