Hey folks I'm having some trouble with this question in my homework: 1. The problem statement, all variables and given/known data A man at the top of a building throws an object straight up at a speed of 10 m/s. The object hits the ground 5 seconds latter. For the purpose of this problem the assumed environment is a vaccum. a) What is the highest point the object reached? b) What's the height of the building? c) At what speed does the object hit the ground? 2. The problem How does the 10 m/s speed relate to the 9.8 m/s^2 gravitational acceleration, does it just slow down the object at -9.8 m/s^2 ?
