Finding initial velocity in free fall with given meters.

Click For Summary

Homework Help Overview

The discussion revolves around determining the initial velocity of a ball thrown by a juggler to reach a height of 3.0 meters. The context involves concepts of free fall and projectile motion.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the relationship between the motion of the ball going up and coming down, suggesting that the upward and downward motions are symmetrical. There are references to using equations of motion to analyze the problem, with some participants questioning which specific equations are applicable given the known and unknown values.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the problem. Some guidance has been offered regarding the symmetry of the motion, but no consensus or resolution has been reached yet.

Contextual Notes

Participants are considering the values they have and those they need to apply the equations of motion effectively. There may be constraints related to the specifics of the problem setup that are still under discussion.

The Attempt at a Solution


You would use the fact that falling from the ceiling to his hand mirrors his toss to the ceiling.
One is travel up - the other down
One starts at high speed and finished at zero speed, the other starts at zero speed and finishes at the same high speed.
 
Recall the equations for motion, time and displacement and see which one fits. For that you have to see what values you know and what you do not know.
 
thanks.
