Homework Help Overview

The discussion revolves around a projectile motion problem where the original poster seeks to determine the initial vertical speed, horizontal speed, and launch angle of a projectile, given only acceleration and distance. The context involves analyzing the motion of a ball projected upward.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the potential confusion between vertical and horizontal displacements, noting that the vertical displacement pertains to the ascent to maximum height while the horizontal displacement covers the entire trajectory. There is mention of needing to incorporate vertical acceleration into the equations.

Discussion Status

Some participants have pointed out discrepancies in the original poster's understanding of the problem setup, specifically regarding the treatment of displacements and accelerations. There is an ongoing exploration of the implications of these observations, but no consensus has been reached.

Contextual Notes

Participants reference the need for clarity on the definitions of vertical and horizontal components in the context of projectile motion. There are also indications of previous discussions on similar problems, suggesting a recurring theme in the understanding of projectile motion dynamics.

1. You have mixed up vertical and horizontal displacements.
2. The given vertical displacement is from launch to max height, but the given horizontal displacement is for the whole trajectory.
3. Only the horizontal acceleration is zero. You need an equation involving vertical acceleration.
