So as to to find introductory physics more though-provoking for varsity students, University of Toledo physics professor Scott Lee has printed a fresh paper that poses an engrossing quiz: might perchance file-breaking sprinter Usain Flow outrun the crested dinosaur Dilophosaurus? The therapod became popularized by the movie “Jurassic Park,” even supposing, you might perchance perhaps perhaps be disenchanted to be taught, there is no evidence the dinosaur might perchance spit acid.
For some college students, an introductory physics route might perchance be their easiest exposure to the sphere of watch — and, as a rule, they’d impartial to find the topic as dry as it goes to be spirited. Lee has tackled this project by rising numerous actions that’ll support college students no longer easiest be taught some physics fundamentals, but moreover revel within the time they employ studying. Case in level? His fresh paper printed in “The Physics Teacher” no longer easiest provides a stress-free quiz but moreover supplies an solution utilizing science.
Most folks couldn’t outrun this dinosaur

The quiz is modest: might perchance Usain Flow buy a 100-meter bustle in opposition to a bipedal dinosaur that weighed around 900 kilos? The quick and subtle solution is yes, and it wouldn’t even be a discontinuance bustle. Lee provides all the suggestions wanted to handbook college students thru the technique of answering the quiz, doing so in a attain that’ll support them “execute computation abilities” and discover about one-dimensional (1D) kinematics.
The physics professor explained to Phys.org that presenting the science with dinosaur questions has proven favorite amongst college students, pointing out, “Fairly a number of physics majors admire, through the years, taken this celebrated training route proper because they mediate dinosaurs are so wintry.”
Lee selected the Dilophosaurs for this quiz because, based mostly totally mostly on the paper, devices of the dinosaur indicate its top working flee became likely subtle around the same common tempo Flow finished at some level of his file-breaking hunch in 2009. The paper provides the math compulsory to unravel this puzzle, crunching the numbers to repeat that Flow would beat the dinosaur in this hypothetical hunch by as a minimal two seconds. Why would a human runner admire the advantage? In step with Lee’s work, Flow has quicker acceleration than the Dilophosaurus would, with the paper concluding he would “admire no effort” beating the beastly opponent.
