Externet Posted May 22, 2006 Share Posted May 22, 2006 Hi. A toy car receives the impact of a horizontally going projectile onto its solid, metallic, vertical rear bumper, and the projectile bounces back. The same toy, weighing the same as before with a springy or rubber bumper, receives the same projectile and it does not bounce backwards at all, just drops vertically after impact. Which case will push the car more distance because of the impact ? Miguel Link to comment Share on other sites More sharing options...
