Homework Help Overview

The problem involves a basketball player leaping from a stationary position and reaching a height of 1.0 m. The main question is to determine how long the player is in the air during the jump.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss the use of kinematic equations to relate displacement, acceleration, and velocity. There is a focus on determining the initial velocity needed to solve for time in the air.

Discussion Status

Participants are actively engaging with the problem, exploring different equations and clarifying the relationships between variables. Some have suggested using specific SUVAT equations, while others are questioning the assumptions about initial and final velocities.

Contextual Notes

There is a recognition of the need for additional equations to find the initial velocity, and participants are considering the implications of the upward and downward motion in their calculations. The discussion includes a mix of correct and incorrect assumptions that are being examined.

s = Vt - 0.5 at2
1=0-0.5(-9.8)t^2
1=-0.5(-9.8)t^2
t=0.45 s

Thanks! Is that better?

Looks good.

Great, thanks again! So is this my final answer, or is that just the time it took for him to go *up*?

Well spotted, I'd missed that. Yes just the time to go up. The time to come down will be the same.

Great, thanks!
