A rock is thrown downward from an unknown
height above the ground with an initial speed
of 28 m/s. It strikes the ground 4.4 s later.
Determine the initial height of the rock
above the ground. The acceleration of gravity
is 9.8 m/s

An object is released from rest on a planet
that has no atmosphere. The object falls
freely for 5.76 m in the first second.
What is the magnitude of the acceleration
due to gravity on the planet?

  1. Initial speed = 28m/s
    time = 4.4s
    Acceleration = 9.8

    Just plugin the numbers into this formula and u will get the answer.

    S=ut+1/2*a*t^2

  2. Hey, I was doing just fine before I met you
    I drink too much and that's an issue
    But I'm OK
    Hey, you tell your friends it was nice to meet them
    But I hope I never see them
    Again

    I know it breaks your heart
    Moved to the city in a broke-down car
    And four years, no calls
    Now you're looking pretty in a hotel bar
    And I, I, I, I, I can't stop
    No, I, I, I, I, I can't stop

    So, baby, pull me closer
    In the back seat of your Rover
    That I know you can't afford
    Bite that tattoo on your shoulder
    Pull the sheets right off the corner
    Of that mattress that you stole
    From your roommate back in Boulder
    We ain't ever getting older

    We ain't ever getting older
    We ain't ever getting older

    You look as good as the day I met you
    I forget just why I left you,
    I was insane
    Stay and play that Blink-182 song
    That we beat to death in Tucson,
    OK
