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

AI Thread Summary
To experimentally determine the maximum range of a projectile without using the standard equation, one can launch the projectile at various angles and measure the resulting distances. The experiment should be conducted on a football field, focusing on maintaining a constant launch speed. Participants discussed using the relationship between height and range, suggesting that the equation R = 4H/tan(theta) could be applicable. The goal is to identify the angle that produces the maximum range while adhering to the constraints of the experiment. This approach emphasizes hands-on experimentation and data collection to derive conclusions about projectile motion.

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 independant 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?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
