The reason that the kinetic energy of book hits the ground with 40.0 J is impossible. Introduction: The gravitational work energy is conservative in nature that means the initial energy of the system is equal to the final energy of the system. Due to conservative nature, energy can be transform to another form but never terminate.

The de-excitation of a state occurs by competing emission and relaxation processes. If the relaxation mechanisms are very effective:a) the emission of radiation is largeb) the emission of radiation is smallc) the emission occurs at a shorter wavelengthd) the de-excitation occurs only by emission processes

m C A block of mass m slides down a ramp of height hand collides with an identical block that is initially at rest. The two blocks stick together and travel around a loop of radius R without losing contact with the track. Point A is at the top of the loop, point B is at the end of a horizon- tal diameter, and point C is at the bottom of the loop, as shown in the figure above. Assume that friction between the track and blocks is negligible. (a) The dots below represent the two connected blocks at points A, B, and C. Draw free-body dia- grams showing and labeling the forces (not com ponents) exerted on the blocks at each position. Draw the relative lengths of all vectors to reflect the relative magnitude of the forces. Point A Point B Point C (b) For each of the following, derive an expression in terms of m, h, R, and fundamental constants. i.
