How Can You Experimentally Determine the Maximum Range of a Projectile?

Click For Summary

Homework Help Overview

The discussion revolves around designing an experiment to determine the maximum horizontal range of a projectile, specifically a frictionless, spherical ball, without using the standard projectile motion equation.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the constraints of not using the projectile motion equation and discuss potential experimental designs, including launching the projectile at different angles. Questions arise about the constancy of launching speed and the nature of independent and dependent variables in the experiment.

Discussion Status

Participants are actively engaging in the design of the experiment, with some suggesting methods to find the maximum range through varying angles. There is a recognition of the limitations imposed by the homework guidelines, and multiple interpretations of how to proceed are being explored.

Contextual Notes

Participants note that they are restricted from using the standard formula for projectile motion and must identify independent and dependent variables for their experiment. The setting for the experiment is specified as a football field.

how do you determine the maximum range w/o using the equation dx= v^2 sin2 feta/g

because i need to design an experiment to figure out the maximum horizontal range of a frictionless, spherical ball
 
Physics news on Phys.org
Why not use that equation?
 
because we're not allowed to..
 
can you describe a little more about the experiment you need to design?

are you supposed to launch the projectile at different angles and find the angle at which the range is maximum?

is the launching speed constant?
 
a we were told was that were not allowed to use the special formula(he one i told you about before, and that we're to find the max range of it with an independent and dependat variabl(range)...that's all and it should be be taking place on a football field...i was thiking to do what you just said but how could i if i can't use that formula

tan(theta) = 4H/R

R = 4H/tan(theta)

how about this equation?
