Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Q2. As shown in the image below, the freight cars A and B are approaching each other, and they have a mass of mA = 23 Mg and mg = 14 Mg, respectively. The directions of their initial velocities are shown in the image, and the speeds are VA,1 4.3 m/s and v³,1 = 2.9 m/s. Determine the velocity of A after collision if the cars collide and rebound, such that B moves to the right with a speed of 1.8 m/s. Right is considered the positive direction and negative sign must be included if A moves to the left after the collision. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. A Your Answer: VA,1 Answer units B VB.1 =
A railroad car having a mass of 15000 kg is coasting at 1.5 m/s on a horizontal track. At the same time another car having a mass of 12000 kg is coasting at 0.75 m/s in the opposite direction. If the cars meet and couple together, determine the speed of both cars just after the coupling.
During an Olympic 100-m sprint race, Usain Bolt, the world record holder in that race, quickly accelerates to his top speed of 12.4 m/s. Analysis of his technique has shown that each of his feet make contact with the ground for 0.0800 s, exerting a force of magnitude 2.80 x 10° N during this contact. This allows the 94.0 kg Bolt to leap forward and remain airborne for 0.120 s until the next foot touches the ground. (Ignore air resistance.) (a) What are the magnitudes of the horizontal and vertical components of the force (in N) Bolt's feet exert on the ground? (Round your answers to at least three significant figures.) horizontal N vertical (b) Assuming that the sprinter accelerates at a constant rate while his feet are in contact with the ground and does not slow down when he is airborne, by what amount does Bolt's horizontal speed (in m/s) increase with each step?

In order to avoid the extra energy and time required in starting and stopping, whenever possible trains are loaded through a vertical chute which drops heavy loads directly into the moving train car beneath. The modern average locomotive and a single empty train car have a mass of approximately 23000 kg. If the train passes beneath shoot with a velocity of 6 meters per second when a 5200 kg load of gravel and stone is dropped into the empty train car beneath determine b) the final velocity of the train after the load has been delivered.
