An open lift is descending at a steady speed of 2.5 m/s relative to the ground as shown in the figure below. A person in the lift throws a small box horizontally outward from the lift with a speed of 10.0 m/s. Determine the magnitude and direction of the initial velocity of the box relative to a person standing on the ground.
