Question

A man moves relative to boat at an angle of 45° with the direction of flow of water with a speed 0 v 2 as shown in the figure. Water flows with a velocity 0 v i 2 and the boat moves perpendicular to water current relative to water with a velocity 0 v 2 . If the rain appears to fall vertically with a speed v0 relative to man, the magnitude of actual velocity of the rain is
