3. Suppose a meteorite collides with Earth with a force of 6.41*1012N.

A. What is the mass of the meteorite if it's impact speed is 10 km/s so that it has an acceleration of approximatley -1.00*108 m/s2

I know I want to use an equation from Newton's second law but what equation do I use? and how to I change it so I can plug it in(if I need to)?

I figured out I want to use [tex]\sum_{\rm all}\bold{F}\,=\,m\frac{d(\bold{v})}{dt}\,=\,m \bold{a}[/tex] (I believe) and I know I need these can anyone help me?

Acceleration = Net force divided by mass

Net force = rate of change of momentum

Net impulse = change of momentum
