Andrew jumped on a rocket, sending it straight up, and timing its motion. He sees that the rocket goes by the top of the library after .40 seconds and then reaches the top of the library again after a total elasped time of 3.7 seconds.
a) draw and label the problem
b) How high is the Library above the point where the rocket was lauched(ignore air resistance)
c) How fast was the rocket going at lauch
d) if the timer was precise to +/- .02 seconds for each reading, what is the uncertainty in your measurements of the height of the library, and the velocity of the rocket? Why?
