Particle Acceleration

  1. Oct 5, 2007 #1
    A particle's acceleration is described by the function a_x =(10 -t) m/s^2, where t is in s. Its initial conditions are x_0 =0 m and v_0x =0 m/s at t =0 s.

    At what time is the velocity again zero?

    I am having a hard time setting this problem up with where to begin if someone could help me with a formula that would be much appreciated.

    Ax = (10-t)m/s^2
    Xi = 0 m
    Vi = 0 m/s
    t = 0 s

    since acceleration is A = (Vf-Vi)/t

    Hint. You are given a = f(t). How can you get v from this? Think calculus.
