Situation 03. A yacht is approaching the dock at 45 cm/s. A landing equipment was left on the dock and needs to be thrown to the yacht just before it can dock. The equipment is thrown 15 m/s at 30° with the vertical from the top of a tower 8.75m above the ship deck. Compute the distance from the dock to the yacht should the yacht be at the instant the equipment is thrown.
