Suppose an object is launched from Earth with 0.52 times the escape speed. How many multiples of Earth's radius (RE 6.37 x 106 m) in radial distance will the object reach before falling back toward Earth? The distances are measured relative to Earth's center, so a ratio of 1.00 would correspond to an object on Earth's surface. For this problem, neglect Earth's rotation and the effect of its atmosphere For reference, Earth's mass is 5.972 x1024 kg. Your answer is...
