A car drives up a straight incline of 4.8 km in length and .3 km in height. The car moves up the incline at a steady speed of 16 m s^-1, with friction force being 500 N and total weight of car and driver being 12000 N. From the top of the incline, the road continues downwards in a straight line. At the point where the road starts to go downwards, the driver stops the engine and allows the car...
Solve the following using the 5-step process. The speed of a freight train is 75 mph slower than the speed of a passenger train. The freight train travels 340 miles in the same time that it takes the passenger train to travel 490 miles. Find the speed of each train. Instructions: Enter your answer as a whole number, fraction, or radical. When entering units, type without capitals e.g. mph, feet, meters, yards, etc. The freight train is travelling at Number...
2. An object is thrown straight upwards at a speed of 25 m/sec. How high will it rise? How fast will it be moving when s it is 20 m high? How long will it take to reach this height on + the way up? On the way down?
6. Two cars are traveling along a straight road. Car (A) maintains a constant speed of 80.0 km/h; car (B) maintains a constant speed of 115 km/h. At t = 0, car (B) is 31.0 km behind car A. How far will car (A) travel from t-0 before it is overtaken by car (B)? km 7. A ball is thrown vertically downward from the edge of a bridge 25.0 m high with an initial speed of 18.0 m/s. The ball...
