13. Braking Distance : The distance that a car travels between the time the driver makes the decision to hit the brakes and the time the car actually stops is called the braking distance. For a certain car traveling v , the braking distance d is given by d = v + 1/2c V2

• Find the braking distance when v is 50 km/h.
• If a driver decides to brake 120 metre from a stop sign, how fast can the car be going and still stop by the time it reaches the sign?

14. Eiffel Tower: The Eiffel Tower is a landmark and an early example of wrought-iron construction on a gigantic The lower section consists of four immense arched legs set on masonry piers. The legs curve inward until they unite in a single tapered tower. Platforms, each with an observation deck, are at three levels; on the first is also a restaurant.

The tower, constructed of about 7000 tons of iron, has stairs and elevators. A meteorological station, a radio communications station, and a television transmission antenna, as well as a suite of rooms that were used by Eiffel are located near the top of the tower.

• For a person standing 324 m from the center of the base of the Eiffel Tower, the angle of elevation to the top of the tower is 45c . How tall is the Eiffel Tower?
• A car is moving at uniform speed towards the Eiffel It takes 15 minutes for the angle of depression from the top of tower to the car to change from 30c to 60c . After how much time after this, the car will reach the base of the tower?
