Kinematics cheetah Problem

  1. Sep 16, 2009 #1
    Kinematics Problem!!!

    A cheetah can accelerate from rest to 26.0 m/s in 2.18 s. Assuming the acceleration is constant over the time interval, what is the magnitude of the acceleration of the cheetah?
    ANSWER=1.91x10^1m/s^2

    What is the distance traveled by the cheetah in these 2.18 s?
    2.83x10^1m

    A runner can accelerate from rest to 5.90 m/s in the same time, 2.18 s. What is the magnitude of the acceleration of the runner?
    2.71m/s^2

    ****I DONT KNOW HOW TO DO THIS LAST PART BELOW PLEASE HELP!
    By what factor is the cheetah's average acceleration magnitude greater than that of the runner?

    Re: Kinematics Problem!!!

    Wouldn't that just be the runner's acceleration divided by the cheetah's?
