SUMMARY

The discussion focuses on calculating the speed and momentum of a Tyrannosaurus rex (T. rex) based on provided data. The key parameters include a time interval of 0.62 seconds between footprints and a distance of 10 meters for two footprints. The maximum speed is established as approximately 8 m/s, with the mass of the T. rex being 7000 kg. The relevant equation for this scenario is v = u + at, where the acceleration (a) is zero due to constant speed.

PREREQUISITES
  • Understanding of basic physics concepts such as speed, distance, and time.
  • Familiarity with kinematic equations, specifically v = u + at.
  • Knowledge of momentum calculation, defined as mass times velocity.
  • Ability to interpret and analyze motion based on given parameters.
NEXT STEPS
  • Study the derivation and application of kinematic equations in physics.
  • Research the concept of momentum and its calculation in various contexts.
  • Explore real-world applications of speed calculations in paleontology.
  • Learn about the biomechanics of dinosaur locomotion and how it relates to modern animals.
USEFUL FOR

Students studying physics, paleontologists interested in dinosaur locomotion, and anyone looking to understand the principles of speed and momentum in a practical context.

Homework Statement



calculate speed and momentum of T REX. Time between footprints is 0.62s - there are 2 footprints in a 10m distance, speed is constant - I need to show that the maximum speed is about 8ms-1 - how to I go about doing this? Help I have no idea
Its mass is 7000kg.

Homework Equations



v=u+at


The Attempt at a Solution



8ms-1 = 0 + at but time is what time between footprints is only known time?
 
Physics news on Phys.org
They tell you that the speed is constant. Knowing this, can you use the time given and the distances given to find v? What formulas for v apply when v is constant?
