SUMMARY

The physics problem discussed involves calculating the maximum height Tarzan reaches while swinging on a vine, given an initial horizontal velocity of 8.0 m/s. Using the equation for kinetic and potential energy, the height is determined to be 3.2 meters, derived from the formula h = (1/2)(v^2)/g, where g is the acceleration due to gravity (10 m/s²). The discussion clarifies that without a vertical component of velocity, Tarzan would not leave the ground, emphasizing the importance of understanding both horizontal and vertical motion in this context.

PREREQUISITES
  • Understanding of basic physics concepts, including kinetic and potential energy.
  • Familiarity with the equations of motion, specifically 1/2mv² = mgh.
  • Knowledge of gravitational acceleration (g = 10 m/s²).
  • Ability to analyze motion in two dimensions (horizontal and vertical components).
NEXT STEPS
  • Study the principles of conservation of energy in physics.
  • Learn about projectile motion and its equations.
  • Explore the concept of vector decomposition in physics.
  • Practice solving similar problems involving energy and motion.
USEFUL FOR

High school physics students, educators teaching mechanics, and anyone interested in understanding the dynamics of motion and energy conservation.

Need Help Grade 11 physics question!

The question is something like this I am not sure exactly because it was on my test.

Tarzan is running at 8.0 m/s and jumps onto a vine. How high above the bottom of his swing will he go ?

Plz help i have no clue how to do this
 
Physics news on Phys.org
1/2mv^2 = mgh
1/2v^2 = gh
h=1/2(8)^2/10=3.2 m
 
You must know his velocity in the Y direction or up. If you were given and angle, then it can be broken down.

If he only has a velocity of 8 m/s in the X direction, then he will not leave the ground.

thanks a lot i figured it out i got the same answer as u 3.2 i think i need to find the velocity so do i just double the 3.2 and make it 6.4?
 
meister hit the nail on the head.
What do you mean find the velocity? When he starts off, his X velocity is 8 and his Y is 0; at the peak of his swing, both x and y are 0.
 
I see now, I was reading it as how far up he would jump onto the swing?
