Question

In 1985, aspider with a mass of 112 g was caught in surinam, south America. (Recall that the smallest dog in the world had a smaller mass.) Suppose a spider with this mass runs at a certain unknown speed when it collides inelastically with another spider, which has a mass of 96.0 g and is at rest. Find the fraction of the Knetic energy that is dissipated in the perfect inslastic collision. Assume that the resting spider is now on a low-friction surface. Do you need to know the first spider's velocity to calculate the fraction of the dissipate kinetic energy? Please do the problem step by step

Explanation / Answer

use conservation of energy: v is spider velocity,,,,v' is his velocity ofter collision and v'' is velocity of spider at rest .5*.112*v^2 = .5*.112*v'^2 + .5*.096*v''^2, from conservation of momentum: .112v = .112v' + .096v'', so we have two equation and three unknown so we need to know spider velocity to further calculate,
