1. The problem statement, all variables and given/known data How high above the surface of the Earth must a mass be located so its gravitational potential energy is only 17.00% of its value on the surface? 2. Relevant equations PEg=(-GMm)/r, PElocal= mgy where y is height the object can fall 3. The attempt at a solution I've tried a couple of different things but all my variables cancel out. (-GMm)/r1=0.17((-GMm)/r2 r1/0.17=r2 If I randomly set r1 to be 1 r2= 5.88235 but that doesn't make sense because if you raise an object by 5m it would have a greater PEg Any suggestions on where to go? Thanks!!
