1. The problem statement, all variables and given/known data You have a 10kg object that is thrown down a building. The distance from the ground to the building is 50m. The initial velocity of the object is 5 m/s. What is the applied force and what force does the object hit the ground with? 2. Relevant equations Fapp= Fnet+Fg Fnet=acceleration x mass Fg=mass(g) 3. The attempt at a solution I don't even know where to start on this question. I don't think I can assume the acceleration of the object is 9.81 m/s/s because it is thrown down not dropped. Without acceleration I can't find Fnet. Without Fnet I can't find Fapp. All I know is Fg=mass(g)= 98.1N. Can someone help me on this?
