Two kids decided to play with their toys, balls. The first kid is on the ground (0.00 meter), whereas the second kid is on top of a 10.00-meter tall building. The second kid threw his ball at the same time that the first kid throws another ball upward. At the time that the first kid’s ball reaches its maximum height, the two balls will collide. iii) If the two balls experienced inelastic collision, compute for the time it will take for the two balls to reach the ground (given that their starting speed is 1/2√g(10.00m) ).

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.
