The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance d apart on the same axle (Fig. P10.68). From the angular displacement Δθ of the two bullet holes in the disks and the rotational speed of the disks, we can determine the speed v of the bullet. Find the bullet speed for the following data: d = 55 cm, ω = 850 rev/min, and Δθ = 31.0°. http://www.webassign.net/pse/p10-65.gif

    Depends on the question - but I'd say, just post it 'regularly', so others see it, too ;)
