An observer on the ground concludes that the forces on the cart are the force of gravity and the support from the track. If an object is accelerating vertically, the normal force is less than or greater than the weight of the object. If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points conservation of energy is the most direct way to understand the problem.

How fast is the coaster moving? WebRoller coaster trains have wheels that run on the sides (side friction or guide wheels) and underneath the track (upstop, underfriction, or underlocking wheels) as well as on top of it (road or running wheels); these lock the train to the tracks and prevent it from jumping the track.The side wheels can be mounted on the outside or inside of the train, depending on 1 of 1 Draw the free body diagrams for the car going around a horizontal curve, the bottom of a vertical loop, and the top of a vertical loop in which the cart is upside down.

The frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. (Remember that friction always acts in the direction opposite that of motion or attempted motion between surfaces in contact. Again, a reasonable value. The problem with trying to answer is that your questions are far to general. Because essentially no energy is lost from the system (you are told friction and air resistance are negligible,) the amount of energy in the system remains constant throughout. A constant resultant force of(2.0i+4.0j)N(2.0i^+4.0j^)Nthen acts on the object for 3.0 s.
