英语翻译
A small bead of mass m is free to slide along a long,thin rod without any friction.The rod rotates in a horizontal plane about a vertical axis passing through its end at a constant rate of f revolutions per second.Show that the displacement of the bead as a function of time is given by r(t)=A1ebt +A2e–bt ,where r is measured from the axis of rotation.Find the expression for the constant b.Also,how would you determine the constants A1 and A2?
