Consider a hypothetical dense astronomical object with a mass of 2 x 1030 kg (about the mass of the sun), and a radius of 1.4 x 1014m. Assuming you could stand on the surface of this object, if you fired a gun straight into the air, how high above the surface would the bullet go before turning around? The mass of a bullet is 5.0g and its speed is 800 m/s when it leaves the gun. Ignore any frictional or drag forces on the bullet. a.) 3.3 x 104 m b.) 7.1 x 1013 m c.) 2.1 x 1014 d.) 4.2 x 1014 e.) Infinitely high (it escapes from the surface and never turns around). m m
