What is the escape speed from a 300-km-diameter asteroid with a density of 2500 kg/m3?

Solution to 53P Step 1 of 3 Introduction Escape speed of an object from an planet is given by v. Escape speed is directly proportional to square root of mass of the object and inversely proportional to square root of radius of the planet. Given data: Diameter of the asteroid:300km 3 Radius of the asteroid:150km=150x10 m 3 Density of the asteroid:2500 kg/m
