Calculating the Vertical Height of a Kangaroo Jump

Click For Summary
SUMMARY

The discussion focuses on calculating the time a kangaroo is in the air after jumping to a vertical height of 2.3 meters. The user claims to have derived a time of 0.68 seconds using kinematic equations but seeks clarification on the methodology. The relevant equations for this calculation include the four kinematic equations, which are essential for solving motion problems in physics. The user expresses a desire for a detailed explanation of the solution process to verify their answer.

PREREQUISITES
  • Understanding of kinematic equations in physics
  • Basic knowledge of vertical motion and gravity
  • Familiarity with the concept of maximum height in projectile motion
  • Ability to manipulate algebraic equations for solving physics problems
NEXT STEPS
  • Review the four kinematic equations and their applications in vertical motion
  • Learn how to derive time of flight from maximum height in projectile motion
  • Explore examples of similar problems involving vertical jumps
  • Study the effects of gravity on projectile motion and time calculations
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in understanding the principles of motion related to jumps and projectile trajectories.

Homework Statement


A kangaroo jumps to a vertical height of 2.3 m. How long was it in the air before returning to Earth?


Homework Equations



kinamatics

The Attempt at a Solution



i got .68 which i think is rite but i don't know what do you get?
 
Physics news on Phys.org
I would much prefer to see HOW you arrived at that answer. Under "relevant equations" you have "kinematics" which NOT an equation! What equations did you use?
 
the four kinematic equations

i used all of them and still derived at .68
