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
