Question


A rod of mass 'M' and length 'L' is placed on frictionless horizontal surface. Rod is given an angular velocity ω0 as shown in figure. When rod rotates by 90, it hits a stationary hinge and gets attached to it. New angular velocity is ω such that ω=nω0. Here n is . (Answer upto two digits after the decimal point.)

Solution

By, conservation of angular momentum about the hinge
Li=Lf

ML212ω0=ML23ωω=ω04=0.25ω0
n=0.25
