Rank the vertical component of velocity?

Click For Summary

Homework Help Overview

The discussion revolves around ranking the vertical component of the initial velocity for different projectiles based on their launch angles. Participants are exploring the relationships between angle and vertical velocity components.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss using the sine of angles to rank the vertical components, questioning the correctness of this method. There is also a mention of visual comparisons and maximum values.

Discussion Status

Some participants are seeking clarification on why their rankings may be incorrect, while others are exploring the implications of their findings regarding maximum velocities at landing. There is an ongoing examination of the initial assumptions made about the angles and their effects.

Contextual Notes

Participants reference feedback from an online program indicating incorrectness in their rankings, prompting further inquiry into the assumptions and calculations involved.

Homework Statement


Rank the vertical component of the initial velocity of each projectile, greatest first.

Homework Equations


n/a

The Attempt at a Solution


I took the sine of the angles, the angles are ranked B>A>C>D you can see this visually as well as looking at the maximums. why isn't this correct?

The online program said i was incorrect. I solved that one, but now i am trying to find which one has the maximum velocity at the landing area
