1. The problem statement, all variables and given/known data The movie 'The Gods Must Be Crazy' begins with a pilot dropping a bottle out of an airplane. It is recovered by a surprised native below, who thinks it is a message from the gods. If the plane from which the bottle was dropped was flying at a height of 500m and the bottle lands 400m horizontally from the initial dropping point, how fast was the plane flying when the bottle was released? 2. Relevant equations I know this isn't an equation but I think it might be relevant to know the accelaration rate... I'm to use g=10m/s/s for this question. 3. The attempt at a solution So I've drawn myself a picture on my notebook with a plane travelling and this guy dropping a bottle... and I've made different frames, showing that the plane is travelling little by little. Well. To list the knowns and unknowns, I have this: distance from ground to plane: 500m distance between dropping point and landing point (horizontally): 400m speed the plane was travelling at: UNKNOWN We just started this section... and I'm struggling. I don't wanna feel like I should never have taken IB high physics... at this rate, I SO will. Please help me understand this!!
