P. 3797. On a horizontal frictionless table a stick of mass M, length of L and of homogeneous mass distribution is standing.
a) With what velocity had a small body of mass m slid into it, if the stick hit the table after a turn of an angle ?
b) How far was the mass center of the stick from the small body at this moment?
(The collision of the small body and the stick is perfectly elastic.) (Data: M=0.6 kg, m=0.2 kg, L=0.8 m, =60o.)
