How does one go about solving this?


A skateboard rider starts from rest and accelerates at a constant +.50 m/s^2 for 8.4s. What is the riders displacement?

  • physics -

    X = (1/2) a t^2
    a is the acceleration
    t is the time
    X is the displacement

    The formula applies when the initial velocity is zero, as in this case.

  • physics -

    thanks! I forgot the formula >.<
