**1. Homework Statement**

A neutron star has a mass of 2.0 x 10

^{30}and a radius of 5.0 x 10

^{3}. Suppose an object falls from rest near the surface of the star. How fast would it be moving after it had fallen a distance of 0.010 m? (Assume that the gravitational force is constant over the distance of the fall, and that the star is not rotating.)

**2. Homework Equations**

(a) F=(G*m

_{1}*m

_{2})/r

^{2}

(b) F=ma

(c) V

^{2}=V

_{o}

^{2}+ 2ax

**3. The Attempt at a Solution**

Using equation (a), I found the force to be about

**1.068 x 10**

^{43}NUsing equation (b), I found the acceleration to be

**5.338 x 10**

^{12}Using equation (c), I found the velocity to be

**231042.68 m/s**after the object had fallen a distance of 0.01 m.
