A college student wants to toss a textbook to his roommate who is leaning out of a
window directly above him. He throws the book upwards with an initial velocity of 8.0
m/s. The roommate catches it while it is travelling at 3.0 m/s [up).
a) How long was the book in the air?
b) How far vertically did the book travel?
c) Redo the problem, and have the roommate catch the book as it is travelling 3.0
m/s [down]. What is the time and displacement now? Do you notice anything?
