Discussion Overview
The discussion revolves around determining the flight time and heights of two balls thrown vertically. Participants explore the application of kinematic equations and projectile motion principles to solve the problem, focusing on both time and height calculations.
Discussion Character
- Technical explanation
- Mathematical reasoning
- Debate/contested
Main Points Raised
- One participant calculated the time using the equation 3 + (10 * x) = 13.5 * x, arriving at x = 0.857, but struggled to find the height.
- Another participant requested to see the work done to find the height.
- A different participant proposed using the projectile motion formula y = -4.9t^2 + vo*t*sinO, but noted it did not lead to the correct height.
- One participant questioned the relevance of an angle in the context of vertical motion and suggested the original poster (OP) review basic projectile motion concepts.
- Another participant acknowledged the OP's time calculation as correct but noted the need to replace "vo" with 13.5 m/s and clarified that the angle of projection is 90 degrees for vertical throws. They also provided a corrected height calculation of 7.971 m.
Areas of Agreement / Disagreement
There is no consensus on the correct approach to finding the height, as participants have differing views on the relevance of projectile motion equations and the calculations involved. Some agree on the correctness of the time calculation, while others challenge the methods used.
Contextual Notes
Participants have not fully resolved the assumptions regarding the use of projectile motion equations, and there are unresolved steps in the calculations for height. The discussion reflects varying levels of understanding of the underlying physics concepts.
