Answer to Question #140513 in Physics for camilla

Question

you are suddenly transported 65 million years into the past. right into the path of a tyrannosaurus rex! thinking quickly, you run in a zig zag pattern. explain how your knowledge of newton's law of inertia may just save your life !

Answer 1

I have smaller mass than the T-rex chasing me, so, I have less inertia to change my direction. Since the dinosaur is heavy, his inertia is so high that he can't make zigzags as quick as I run. Thus, little by little I, thanks to my inertia, will be able to run somewhere to the left or right while the T-rex will try to turn.
