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.

Question

1. An object is dropped from the top of a 100-m-high tower. Its height above
ground after 1 sec is 100-4.97 m. How fast is it falling 2 sec after it is
dropped?
