At the bottom, the car has kinetic energy of ½mv2. At the top, the car has kinetic energy of 0. If we ignore friction and wind resistance, the initial kinetic energy is converted to gravitational potential energy of mgh, where the m is again the mass of the car, g is the acceleration of gravity, and h is the vertical change in position of the car. Solving the two equations for h, we get
h=½v2/g=(0.5)(25 m/s)2/(9.8 m/s2)=31.888 m
To find the distance traveled along the road, we use a bit of trigonometry: sin(30°) = h/d = 0.5, so d = 2h = 63.776 meters
Of course, the actual value will be less, due to the friction and wind resistance that we ignored in our calculations.

What will be the cost of 10 if one coasts 25p?
If one "coasts" 25p, it means that one is reducing the cost by 25p. Therefore, if the original cost of 10 is reduced by 25p, the new cost would be 9.75.

How long is a continental slope?
The world's combined continental slope is about 200,000 mi (300,000 km) long and descends at an average angle of about 4° from the edge of the continental shelf to the beginning of the ocean basins at depths of 330 - 10,500 ft (100 - 3,200 m). The slope is most gradual off stable coasts without major rivers and is steepest off coasts with young mountain ranges and narrow continental shelves. Slopes off mountainous coastlines and narrow shelves commonly have outcrops of rock. The dominant sediments of continental slopes are muds; there are smaller amounts of sediments of sand or gravel.
Why are phragmites a problem?
In America, not all phragmites are a problem. There is a native species that does not grow as tall or as invasively as the European variety. The European species of phragmites is extremely invasive. It grows tall, does not provide a good food source and it overruns native species. It grows so aggressively that it can take over entire wetlands. It also will grow in the coasts as well.
What happened in 789 AD?
In 789 AD, the Anglo-Saxon king of Wessex, King Æthelwulf, began his reign. This period was marked by increasing Viking raids on England, particularly along the coasts. Additionally, the first recorded mission to convert the Danes to Christianity took place in this year, led by the Archbishop of Canterbury, which reflected the growing influence of Christianity in the region amid the turmoil from Viking incursions.
