Problem:
A student is running in a track meet started a run by reaching 200m in 30 seconds.She then ran 300m in 30 seconds what was her acceleration? (using GRESA method).
Note:
Distance travelled is equal to 500 meters. Total time is equal to 60 seconds. We need to solve first the final velocity.
Solving for final velocity:
Vf = 500 m / 60 s
= 8.33 m/s
Given Data:
t ( time ) = 60 s
Vi ( initial velocity ) = 0 m/s (from start)
Vf ( final velocity ) = 8.33 m/s
a ( acceleration ) = ? unknown
Solution:
We can use the formula (a = Vf - Vi / t) in order to solve for acceleration
a = Vf - Vi / t
= 8.33 m/s - 0 m/s / 60 s
= 8.33 m/s / 60 s
= 0.14 m/s²
Answer:
The acceleration is equal to 0.14 m/s²

where did you get the 8,33m/s?
