The problem involves a tennis ball shot vertically upward in an evacuated chamber, with an initial speed of 20 m/s. Participants are tasked with determining the peak height the ball reaches and the time it takes to reach that height, while considering the effects of gravity and neglecting air resistance.
The discussion is ongoing, with participants exploring different interpretations of the problem and sharing their reasoning. Some guidance has been offered regarding the equations used in free fall scenarios, but no consensus has been reached on the specific calculations or outcomes.
Participants are working within the constraints of a homework assignment, which may limit the information they can access or the methods they can use. There is also a mention of a home-brew formula that some participants are using, which may not align with standard approaches.
