Sally and Sam are in a spaceship that comes to within 18,000 km of the asteroid Ceres. Determine the force Sally experiences due to the presence of the asteroid. The mass of the asteroid is 8.7 X 10^20 kg and the mass of Sally is 77 kg. For calculation purposes assume the two objects to be point masses.

F = 0.014 N

Explanation:

       where G= Universal Constant of Gravitation = 6.67*10⁻¹¹ N*m2/kg2

       mS = mass of Sally = 77 kg.

       mC = mass of Ceres = 8.7*10²⁰ kg

       rSC = distance between Sally and Ceres = 18,000 km

are there options? cause you ain’t. real specific

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
