The discussion revolves around a physics problem involving kinematics, specifically focusing on calculating average acceleration and final velocity based on given distance and time. The scenario describes a runner starting from rest and reaching a ball after a specified duration.
The discussion is ongoing, with participants sharing their attempts and expressing confusion about the formulas. Some guidance has been provided regarding organizing data and potential equations to consider, but no consensus has been reached on the correct approach or solution.
Participants are working under the constraints of a homework assignment, which may limit the information they can use or the methods they can apply. There is an emphasis on recalling kinematic equations and understanding initial conditions.
ADH said:Branden runs for a ball from a dead stop. It takes him 3 sec to reach it after traveling 10 meters.
What was his average acceleration?
What velocity did he achieve when he caught the ball?
Thank you!
ADH said:My attempt was this. I found the velocity, I think.
For velocity I have 3.333 meters/second.
I was not sure how to find acceleration, or what formula to use.
My teacher gave us this formula: velocity = velocity(sub zero) + at . So should I make a permuatation out of this formula to give me: a = (velocity - velocity(sub zero)) / t ?
So then a = 3.333m/s - (initial velocity) / time
I'm pretty confused. Thanks for helping.
