I push on a wall with a force of 22.7 Newtons. My mass is 83 kilograms, and I am balancing a ball which has mass mass 10.9 kilograms. I am on a frictionless surface, but if I move the ball will drop.  What is the magnitude in Newtons of the force by the wall on me? (You don't need to put the unit, just the number.)

Proper Length

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
