Water flows though the slit at the bottom of a two-dimensional water trough as shown in Fig. P4.50. Throughout most of the trough the flow is approximately radial (along rays from \(O\) ) with a velocity of \(V=c / r\), where \(r\) is the radial coordinate and \(c\) is a constant. If the velocity is \(0.04 \mathrm{~m} / \mathrm{s}\) when \(r=0.1 \mathrm{~m}\), determine the acceleration at points \(A\) and \(B\).
