An object with an initial velocity of 5 m/s accelerates uniformly for 15 s.
(a) If the final velocity is 37 m/s, what is the acceleration?

  • physics -

    Vf=Vi+acceleration*time
    solve for acceleration.

  • physics -

    How far does the object travel during this time?

  • physics -

    You need to memorize some formulas:


    distance= Vi*time+ 1/2 * acceleration*time^2

    or

    distance=average velocity*time
    =(1/2)(Vf+Vi)*time
