Homework Help Overview

The discussion revolves around the kinematics of a thrown football, specifically analyzing the time of flight based on its initial velocity and the time taken to reach the peak of its trajectory.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between the time taken to reach the peak and the total time of flight, with one suggesting a straightforward doubling of the ascent time. Others question the implications of air resistance on the motion.

Discussion Status

The discussion includes various interpretations of the problem, with some participants providing insights into the time of flight and others reflecting on the assumptions made regarding air resistance. There is no explicit consensus, but a productive direction is evident in the exploration of time relationships.

Contextual Notes

Participants are operating under the assumption of no air resistance, which may influence their reasoning about the time of flight.

- A quarterback throws a football at 25 m/s at a certain angle above the horizontal. If it took the ball 3.2 s to reach the top of its path, how long was it in the air?

- I have absolutely no idea how to do this :(

I could be wrong, but if there is no air resistance, then the ball would stay at the same velocity the entire time...

>_> Woops. I didn't notice you were asking about the time...
<_<

hahhaha I think I know this one. It takes the exact amount of time for the ball to go up and to come down so just 3.2 x 2 I believe. but it sounds a bit too easy...
 


^ that was right, thank you so much!
