5. (III) You decide to drop an apple from rest from the observation platform in the statue of liberty's crown. The height h from which the apple is released is 44.5 meters above the shoulders of your friend Robin H., who happens to be standing on the ground directly below you. Robin H. shoots an arrow straight up at the same 772 instant that you release the apple. The initial velocity of the arrow is 24.3 a) How long after you drop the apple will the arrow hit it? b) what is the speed of the arrow right before it strikes the apple?

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.
