Question

a) Fast runners can run with a speed of roughly 10 m/s (over short distances). How big (mass and radius) of an asteroid has an escape speed equal to this
Assume that asteroids have a constant density equal to the average density of the Earth, and that asteroids are spherical.

b) What is the weight of a 100 kg person on the surface of such an asteroid (Hint: remember that weight is a force)

c) If the asteroid is bigger, does the escape speed increase or decrease
