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...

A boat moves through the water with two forces acting on it. One is a 1,875-N forward push by the water on the propeller, and the other is a 1,000-N resistive force due to the water around the bow. (a) What is the acceleration of the 1,500-kg boat? m/s 2 (b) If it starts from rest, how far will the boat move in 25.0 s? (c) What will its velocity be at the end of that time? m/s

15-6. A train consists of a 50-Mg engine and three cars, each having a mass of 30 Mg. If it takes 80 s for the train to increase its speed uniformly to 40 km/h, starting from rest, determine the force T developed at the coupling between the engine E and the first car A. The wheels of the engine provide a resultant frictional tractive force F which gives the train forward motion, whereas the car wheels roll freely. Also, determine...
