3 balls are launched off a tall cliff with the same initial velocity

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving three balls launched from a cliff with the same initial velocity, each at different angles: one upward, one downward, and one horizontally. The focus is on determining which ball will strike the ground with the greatest speed.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the conditions of the problem, questioning the phrasing regarding which ball strikes the ground fastest and clarifying the scenario. Some suggest using kinematic equations to analyze the situation further.

Discussion Status

The discussion is ongoing, with participants clarifying the problem's details and exploring different interpretations. Some guidance has been offered regarding the use of kinematic equations, but no consensus has been reached on the outcome.

Contextual Notes

There appears to be confusion regarding the phrasing of the question, particularly about which ball is being referenced and the intended target. This has led to multiple interpretations of the problem setup.

which will strike the ball at the fastest speed?
-one launched upward at a certain angel
-one launched downward
-one launched perfectly horizontally




I am guessing 1, since it has the additional height to fall under gravity influence

What ball and where is it?

One of the balls is launched horizontally from a cliff.
One of the balls is launched downward from a cliff.
One of the balls is launched upward from a cliff.
 
Yea, three balls are launched...but you are asking which ball would "strike the ball at the fastest speed"? Clearly there is another ball/target that these three balls are aimed at?

Which has the highest speed right before hitting the ground
 
i misstyped. it should be which of these 3 balls strikes the ground with the greatest speed.
 
Instead of guessing, why not try writing out the kinematic equations for each scenario. (You will get a most interesting result)
