    How High Above Earth is Gravity 10% of Sea Level?

    Homework Statement At what height above the Earth's surface is the acceleration due to gravity 10% of that at sea level? Homework Equations F= Gm1m2/r(squared) The Attempt at a Solution I think some how one of the masses is moved over so that F/m=a and I think .10 is multiplied...

    Solving Bottle Thrown with Initial Velocity: Find Final Velocities

    aha, I see the 2.8 now. I had calculated the sq. rt. of 2 / 2 and the only thing I didn't do was multiply that by four. thanks

    Solving Bottle Thrown with Initial Velocity: Find Final Velocities

    it says from the horizon, so I guess the innitial and final heights are the same. I have the answer btw, I just don't know how Kaplan got it. here's the answer...2.8 m/s in both the x an y directions.

    Solving Bottle Thrown with Initial Velocity: Find Final Velocities

    Homework Statement A bottle is thrown with an initial velocity of 4 m/s at 45 degree angle from the horizon. Find its final horizontal and vertical velocities before striking the ocean. Homework Equations change x= innitial velocity (t) + a(t squared) final velocity= innitial velocity...
