    Rotation Problem: determine the number of revolutions

    Just wondering if anyone else had any ideas. I tried rock.freak667's suggestion to use projectile motion equations to get the time. I solved h = 1/2 gt2 for t and got t = 1.366 seconds. This is the same time I got when I just used the equations for constant acceleration (i.e. h = ho +...

    Rotation Problem: determine the number of revolutions

    I think I should have included a picture initially. Please see the quick sketch (not to scale) showing what I am describing. I understand the use of projectile motion equations when items are launched off of a ledge with a significant velocity in the x direction. I don't think this is the...
