SUMMARY

The discussion focuses on calculating the maximum velocity and force of friction for a model rocket weighing 83.8 grams, which accelerates at 5.78 m/s² and reaches a maximum height of 84.99 meters. The force of friction (Ff) is calculated using the formula Ff = μkFn, where the normal force (Fn) is determined to be 82.266 N after converting grams to kilograms. The user expresses confusion regarding the nature of acceleration and its relationship to maximum height, indicating a need for clarification on whether the acceleration is constant or initial.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Knowledge of kinematic equations
  • Familiarity with the concept of normal force
  • Basic grasp of friction coefficients
NEXT STEPS
  • Research the kinematic equation for maximum velocity in projectile motion
  • Learn about the relationship between acceleration, velocity, and height in physics
  • Study the concept of constant versus initial acceleration in motion
  • Explore the calculation of friction coefficients and their application in real-world scenarios
USEFUL FOR

Students studying physics, particularly those interested in mechanics and motion, as well as hobbyists involved in model rocketry and related calculations.

Homework Statement


ok, so i need to find max velocity and force of friction of a model rocket. The rocket weights 83.8 g, accelerates at 5.78 m/ss. Its max height is 84.99 m. please help


Homework Equations


ok for Ff = μkFn
as for Vmax i have no idea


The Attempt at a Solution


ok so i found Fn = 82.266 N because u have to convert grams to kg. Thats all i can figure out.
 
Physics news on Phys.org
a little confused.

is the acceleration constant?

if so then how does it have a max height if it is constantly accelerating?

or is it an initial acceleration?
 
the question is related to my model rocket we launched a week ago, the accceleration is average from initial to the max height. don't know if that makes sense.
