A student and his friend while experimenting for projectile motion with a stopwatch take some approximate readings. As one throws a stone in air at some angle, other observes that, after 2.0s, it is moving at an angle 30^(@) to the horizontal, and 1.0 s after that instant, it is traveling horizontally. Determine the magnitude and the direction of initial velocity of stone.
