A spring is used to launch a block up a frictionless ramp as shown at right. At time t,, the spring is compressed and the block is released from point A. The block moves up the ramp, losing contact with the spring at point B. When it passes point C, the block has a velocity vc directed up the ramp. Imagine a system that includes the block and possibly one or more additional objects. Is it possible to choose a system whose total energy is constant during the interval from t, to t,? If so, state which object(s) must be included in the system. Explain. a. b. Is it possible to choose a system so that the total energy is not constant during the interval from t, to t,? If so, what is the system containing the fewest possible objects for which the energy is not constant during this interval? Explain

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
