The discussion revolves around a kinematics problem involving an Olympic sprinter's acceleration from rest to a top speed of 11.5 m/s over a distance of 15 m. Participants are exploring how to find missing terms such as acceleration and time using kinematic equations.
The discussion is ongoing, with participants sharing their understanding of the problem and questioning the correct formulas. Some guidance has been offered regarding the use of standard kinematic equations, but there is no explicit consensus on the approach to take.
There is a lack of information regarding time, which is a point of confusion among participants. The original poster's question does not specify how to find time, leading to further inquiries about the relationship between distance, speed, and acceleration.
What is s?tiny-tim said:hicneedshelp!
vi = 0
vf = 11.5
s = 15
and you want to find a …
so which of the standard https://www.physicsforums.com/library.php?do=view_item&itemid=204" equations do you think you should use?
tiny-tim said:s is always distance
)tiny-tim said:what times??
(i don't see any times in the question
tiny-tim said:that formula certainly works if you know t
but you only know vi vf and s, and there is a formula using that information
