The escape velocity is a function of a planet’s radius and mass. We also know that the mass of an object is M = ρV where ρ is the mass density and V is the volume. The volume of a sphere is V = (4/3) π R3 a.) combine the formula for the escape velocity with the additional relationships given above and find an expression for the escape velocity as a function of the mass density and radius of a...

please explain the answer
4) The escape velocity on the surface of a planet is given by 2GM R where G = 6.67 x 10-11m2 kg-1 3-2 is Newton's gravitational constant, M is the mass of the planet, and R is the radius of the planet. The escape velocity is the velocity you have to thrown an object so that it does not come back down (better hit the gym!). Write v in terms of average mass density p. Recall...
