← Three 2.0 kg balls sit at the corners of an equilateral triangle of side 0.50 m. What is the gravitational potential energy of the arrangement? (G = 6.67 × 10⁻¹¹ N m²/kg².)Astronauts leaving the Moon must reach its escape speed. Using the Moon's mass, 7.35 × 10²² kg, and radius, 1.74 × 10⁶ m, find that speed. (G = 6.67 × 10⁻¹¹ N m²/kg².) →
