A light elastic string has natural length a and modulus of elasticity 12mg. One end of the string is attached to a fixed point O. The other end of the string is attached to a particle of mass m. The particle hangs in equilibrium vertically below O. The particle is pulled vertically down and released from rest with the extension of the string equal to e, where e> a. In the subsequent motion the particle has speed √2ga when it has ascended a distance a Find e in terms of a.

Hello , i believe scale factor is 13 not 17. Does this affect the ongoing solution ? or if i just change the 17 to 13 ? Because ÖN= 5
The new line of go-karts will have a two-stroke internal combustion engine. The engine generates 35 horsepower at a mean speed of 2000 rpm. The biggest variation in energy per revolution, according to dynamic analysis, is 25% of the mean energy. Design a flywheel to go along with this engine such that the maximum coefficient of speed fluctuation is 0.01. Your design should include all necessary details, such as the design calculations, the appropriate material, detailed dimensions, and manufacturing procedures. Note: As a design problem, there is more than one acceptable solution. One design, though, might be superior to others.
