A roller coaster of mass m rolls down a track with minimal friction. The starting height h1 is 55 m. The coaster starts from rest and is stopped at the end of the ride using a spring with a spring constant k = 7500 N/m. Sprine ONSTANT, K `CoMpRession is ay a) How fast is the coaster traveling just before it enters the loop? m/s b) How fast is the coaster traveling in miles/hr? There are 1.6 km in a mile. mile/h c) How high is the top of the loop (h2) if the coaster travels at 18 m/s at the very top of the loop?

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.
