A parachutist jumps from a balloon at the edge of space (so there is no air resistance). The height the parachutist jumps from rest at is 35,000 m above the ground. What is the speed of the parachutist (in m/s) by the time the parachutist gets down to an elevation of 10,000 m above the ground? Ignore air resistance at these high altitudes. Don't include units in your answer.
