1. The problem statement, all variables and given/known data A hummingbird has a mass of about 1.7 g. Suppose a hummingbird does 0.15 J of work against gravity, so that it ascends straight up with a net acceleration of 1.2 m/s2. How far up does it move? 2. Relevant equations 3. The attempt at a solution I don't know what to do with the net acceleration, but i do know you have to convert 1.7 g to kg... what would the formula do you use?!
