A river of width ‘a’ with straight parallel banks flow due north with speed ‘µ’. The point Oand A are on opposite banks and A is due east of O. coordinate axes OX and OY are takenin the east and north directions respectively. A boat, whose speed is V relative to water,starts from O and crosses the river. If the boat is steered due east and its velocity ‘u’ varieswith x as : u = x (a - x)
