Constant acceleration calculations.

  1. Jan 13, 2010 #1
    1. The problem statement, all variables and given/known data

    an antelope moving with constant acceleration covers the distance between two points 70.0 m apart in 7.0 s. Its speed as it passes the second point in 15.0 m/s .

    a) what is its speed at the first point?
    b)what is the acceleration?

    2. Relevant equations

    what do you mean by relevant equations??
    please give me a little more idea.

    3. The attempt at a solution

    well, honestly im advancing to what my teacher teach on us. because she is absent in the last meeting. :( i figure that X sub 0 is 70.0 m and im stuck at that. i cant figured out how to determine the symbol that i will use.

    i think i can use the formula x = X sub 0 + V sub 0x + 1/2 asubx t^2

    Write out all the standard constant acceleration equations.

    In part 3, choose one of them, and use it to solve the problem … it will have to include vi vf s and a.
