_{w}. Take down to be the positive direction, so that downward velocities are positive and the acceleration due to gravity is the positive quantity g.

Assume that the flower pot was dropped by someone on the floor above you (rather than thrown downward).

So the known variables are... t, L

_{w}, and g.

If the bottom of your window is a height h above the ground, what is the velocity v

_{ground}of the pot as it hits the ground? You may introduce the new variable v

_{b}, the speed at the bottom of the window, defined by

V

_{b}=L

_{w}/t+(g*t)/2.

Express your answer in terms of some or all of the variables h

_{b}, L

_{w}, t, v

_{b}, and g.

I have these equations already... but i don't know where to go about from here...

h

_{b}=v

_{b}+1/2(gt

^{2})

the equation given...

v

_{g}=v

_{b}+g*t

v

_{b}=1/2*g*t

^{2}-h

_{b}

I keep missing one variable... and I'm getting frustrated... :'(

Please help me out.

Thank You,
