Jeremy is very distraught about all the work he has due for school. One day he just could not take it anymore and decides to jump from the roof of the school. While standing on the edge of the roof Jeremy starts to think. His thoughts turn to his favorite class (physics). He knows that the roof of the school is 11.2 meters above the sidewalk. Jeremy calculates the following: a) His velocity just before he would hit the ground. b) How long it would take for him to hit the ground. c) His velocity after 1.15 seconds. After seeing these answers he decided not to jump. Physics saves another life. What were his answers? (60 pts
