Solution: As a ship is approaching the dock at 45.0 cm/s, an important piece of landing equipment needs to be thrown to it before it can dock. This equipment is thrown at 15.0 m/s at 60.0 above the horizontal from the top of a tower at the edge of the water, 8.75 { m m} above the ships deck (the figure .)For this equipment to land at the front of the ship, at what distance D from the dock should the ship be when the equipment is thrown? Air resistance can be neglected.

Problem

As a ship is approaching the dock at 45.0 cm/s, an important piece of landing equipment needs to be thrown to it before it can dock. This equipment is thrown at 15.0 m/s at 60.0 above the horizontal from the top of a tower at the edge of the water, 8.75 above the ships deck (the figure The ship is approaching the dock at 45.0 centimeters per second. The distance between the ship and the dock is labeled as D. The equipment is thrown from the top of the 8.75 meters high tower at the edge of the water in the direction of the ship. It is thrown with velocity of 15.0 meters per second at 60.0 degrees above the horizontal..)

For this equipment to land at the front of the ship, at what distance D from the dock should the ship be when the equipment is thrown? Air resistance can be neglected.
