15. You are watching a baseball game on television that is being broadcast from 4500 km away. The batter hits the ball with a loud "crack" of the bat. A microphone is located 22 m from the batter, and you are 2.0 m from the television set. On a day when sound travels 343 m/s in air, what is the minimum time it takes for you to hear the crack of the bat after the batter hits the ball?

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.
