Do you know how to calculate the acceleration?
no can you help me
Ok, sure. Let's use the formula: \[A = \frac{ Vf - Vi }{ t }\] Can you substitute the values?

can you give me an example
Based on your question, what do you think is the final velocity?
32
32 m/s :) That's your Vf = Final Velocity. What about your initial velocity?
10 m/s
Good! That's your Vi = Initial velocity. What about the time?
3
Great! You can substitute it already :)
thank you i think i got it now
Okiedokes :) Good job!
when i solve the problem should it me m/s or m/s 2
when i solve the problem should it me m/s or m/s 2 @petiteme
