In 1985, a spider with a mass'of 122 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 kinetic energy that is dissipated in the col-lision. Assume that the resting spider is easily movable with respect to the surface on which it is lying. Do you need to know the first spider's velocity in order to calculate the fraction of the dissipated kinetic energy?
