Question

A person exerts a thrust of 100N on the surface of earth while standing. what change in thrust will happen the person lays down. why​

Answer 1

EXPLANATION:

Here, the thrust which is being applied on the surface of the earth is due to the weight of the person standing. If the person lays down on the surface of earth, then also the weight of the person will be the same but the only difference would be in the application of thrust, that the thrust would now be applied on a larger contact area by the person as he lays down. When he was standing, all of the thrust was applied only on that much area which was equal to the person's foot area, but now when he lays down, the thrust is applied by the whole body of the person on the earth's surface perpendicularly. SO TO BRIEFLY ANSWER, THERE WILL BE NO CHANGE IN THE THRUST APPLIED BY THE PERSON. THE ONLY CHANGE WILL BE IN THE PRESSURE APPLIED BY THE PERSON ON THE EARTH'S SURFACE.

HOPE YOU UNDERSTAND MY POINT OF VIEW.
