Packages in an automobile parts supply house are transported to the loading dock by pushing them along on a roller track with very lit- tle friction. At the instant shown, packages B and C are at rest, and package A has a velocity of 2 m/s. Knowing that the coefficient of restitution between the packages is 0.3, determine (a) the velocity of package C after A hits B and B hits C, (b) the velocity of A after it hits B for the second time.

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.

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. 5 pts Question 15
Three identical small spheres, each weighting 2 lb, can slide freely on a horizontal frictionless surface. Spheres B and C are connected by a light rod and are at rest in the position shown when sphere B is struck squarely by sphere A, which is moving to the right with a velocity v0 = (8 ft/s)i . Knowing that θ = 30° and that the velocities of spheres A and B immediately after the impact are vA = (0.5 ft/s)i and vB = (3.75 ft/s)i + (vB)yj, determine (vB)y and the velocity of C immediately after impact.
A 10-kg ball A moving horizontally at 12 m/s strikes a 10-kg block B . The coefficient of restitution of the impact is 0.4 and the coefficient of kinetic friction between the block and the inclined surface is 0.5. Draw the impulse-momentum diagram that can be used to determine the speeds of A and B after the impact.
A spring is used to stop a 50-kg package which is moving down a 20° incline. The spring has a constant k =34 kN/m and is held by cables so that it is initially compressed 50 mm. Knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest. Assume that the kinetic coefficient of friction between the package and the incline is 0.2. 2 m/s 50 kg 8m Cable 20° The maximum additional deformation of the spring in bringing the package to rest is 0.574 x m.
