[SOLVED] Density of Asteroids, Escape Velcoity and Jumping 1. The problem statement, all variables and given/known data The question wants to know the maximum radius of an asteroid that you can escape from by simply jumpibng off. The Variables given: densities = 2500 kg/m cubed radii = 470km downwards height of jump = 1m 2. Relevant equations v(Escape) = sqrt(GM/r) m = d/r cubed V squared = U squared + 2as (for initial jump speed) 3. The attempt at a solution using a = 9.8 and s = 1, I calculated the initial jump speed is 4.43 rearranging the equation for EScape Velocity: v(escape) = sqrt[(G(d/r cubed))/r] v sqyared = (G(d/r cubed))/r v squared = GD/r squared r squared = Gd/v sqyared r = sqrt [GD/v squared] but this isn't giving me the right answer?
