    Uniform acceleration!~

    but i do average speed first still right??im confsued about the midpoint interval :confused:

    Uniform acceleration!~

    yeah but then on question number 3... it says.. the values you calculaed are the average speeds for the time interval, not the speed of the interval. To be more percise, the average speed is the speed at the midpoint of each time interval, and should be plotted there instead of at the end of...

    Hi what formula do i use to find for my question

    i kno v2-v1... but i need to find the initial velocity..mean v1 right?? so how do find v1!

    Hi what formula do i use to find for my question

    how am i gonna get the initial velocity??? with a=delta v/delta t??

    Hi what formula do i use to find for my question

    dleta v means change in velocity:rofl:

    Hi what formula do i use to find for my question

    Homework Statement in a final burst of energy near the end of a bike race, Julia accelerates at 0.32 m/s^2 north for 15 s, attaining a final speed of 18.6 m/s south. what was Julia's initial velocity and how far did she travel while accelerating? The Attempt at a Solution In this case I think...

    I need help with the formula pls

    oh i never knew that lol! thnx:eek:
  20. I

    I need help with the formula pls

    oh ok thnx:tongue:

    I need help with the formula pls

    but do u kno how i would do deceleration?
  22. I

    I need help with the formula pls

    ohh, yes i forgot about that! thanks !
  23. I

    I need help with the formula pls

    v1 and v2 : velocity theres only seconds and one velocity...
  24. I

    I need help with the formula pls

    if so, im not sure how i would get the v1 and v2
  25. I

    I need help with the formula pls

    umm ok so to calculate a) the braking distance...would i use the a= delta v/delta t formula? If so then what do i use next?
  26. I

    I need help with the formula pls

    yes , i know those formula but thanks for pointing those out:tongue: But i'm a little confused on how to find the deceleration!

    Anyone know where I can get previous years' AP Physics C exams?

    oh yes and antiderivative if you do send them to people thanks alot for taking time.
