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...

ah thank you everyone

So since I want mass it would be mass=force/acceleration?

I'm going to be honest idk what that is. I'm guessing Force=Mass*Acceleration?

Basically i have no clue how to do this so I was hoping someone could help me on the formulas with some and explain/show how to set it up. Thanks :) 1. a block and tackle (a system of pulleys) with a mechanical advantage of 48 is used to life a piano 11 m to the third floor of a building...
