    Coulomb's Law and Final Angle of Dust Cobweb

    (I posted this in the wrong section earlier, hopefully i got it right this time...) 1.Homework Statement A dust cobweb is drawn from an initial vertical position toward a nearby wall by an electrostatic force. Assume the cobweb to be like a single dust ball of mass 2.0 x 10^-7g suspended on...

    How Do You Calculate the Velocity of a Ball Thrown from a Moving Train?

    Components completely slipped my mind. Thank you, it worked. I got 12m/s [E49N] so that does sound a bit odd but it's just a random question so I'm sure it doesn't matter if it's realistic

    How Do You Calculate the Velocity of a Ball Thrown from a Moving Train?

    Homework Statement A man on a moving train throws a ball at a parked car. Find velocity of the ball when it hits the car if: train is moving 21 m/s North East; the man is walking 3.0 m/s [E35S] (relative to train) ball is thrown 10.0 m/s [W22S] (relative to man) Homework Equations VBG...
