Question: The velocity field near a stagnation point (see Example 1.10) may be written in the form u = Uox / L v = -Uoy/L Uo

The velocity field near a stagnation point (see Example 1.10) may be written in the form
u = Uox / L v = -Uoy/L Uo and L are constants
(a) Show that the acceleration vector is purely radial.
(b) For the particular case L = 1.5 m, if the acceleration at (x, y) = (1 m, 1 m) is 25 m/s2, what is the value of Uo?
