    Astronaut With Gun and Circular Motion

    Hey I hate to keep bumping this but it's due tomorrow and I want to make sure I'm on the right track at least, thanks!

    Astronaut With Gun and Circular Motion

    any feedback on how I'm interpreting this?

    Astronaut With Gun and Circular Motion

    This says to me, and I'm really just guessing here that we would add the inward velocity and the tangential velocity so that ball will go diagonally to the right? Then I would say for part B that no matter how fast the bullet was shot the ball would still adopt the tangential velocity of the...

    Astronaut With Gun and Circular Motion

    Homework Statement An astronaut (mass mA) in space, tied to the end of a tether of length 10m, is traveling in a circle with constant speed making one revolution every 15seconds. a) Assume that the astronaut fires a spring loaded gun (containing a ball) towards the center of the circle and...

    Solving Friction & Tension Homework Problem

    I'm a little confused with part c in determining if the big mass M will move against the static friction. Mainly since I'm not entirely sure how to determine if there is some increase in Ft that'll cause it to move. Can you make sure I'm doing my math right for it? For M, Fsmax = .55(mg) =...

    Solving Friction & Tension Homework Problem

    Homework Statement A block of mass M = 2m sits on a table and is attached to two other blocks, each having mass m, by strings passing over pulleys as shown (if you need picture let me know, one mass is hanging on the left and the other is hanging on the right). The coefficient of static...

    Rope Sag and Force on a Block Being Pulled

    Thanks for your help, I'm still kind of stuck on the rope sag though. Maybe if I could get some help on a free body diagram for the rope with mass? I have going to the right the Fpull, down Fgravity, and up a Fnormal. Not sure where on the free body diagram for the rope I would put Ftension...

    Rope Sag and Force on a Block Being Pulled

    Homework Statement A block of mass M is pulled along a horizontal frictionless surface by a rope of mass m, as shown. A horizontal force P is applied to one end of the rope. (a) Show that the rope must sag, even if only by an imperceptible amount. Then, assuming that the sag is negligible...
