If a stone is thrown down at 150 ft/sec from a height of 1000 feet, its height after t seconds is given by s= 1000 − 150t − 16t^2.

(a) Find its average velocity over the period [1, 2]. I got -198ft/sec

(b) Estimate its instantaneous velocity at time t = 2.
This is the one I'm having trouble with.

Please find the answer, and let me know how you got it.

Whoever gets answer first gets picked for "Best Answer!"

Rachel’s Rise in Position

As morning dawned upon the dry, cracked ground, the sky unfolded to reveal the sun’s radiant beams, emitting their brilliant flames across the vast horizon. The golden sky awoke, spreading a faint smile across her face. Prickly branches shot forth their naked spokes into the misty air, as if they raised up their cries for rain. There I stood beside the window of my bedroom, as I gazed at the small bush my dad had planted for me. He’d always told me to take care of it, but he would never tell me again. A woman who had too much drink had crashed into my dad’s car, killing him instantly. A tear of sorrow trickled down my cheek, but I brushed it away.

“Mom,” my younger sister’s petulant voice echoed from the other room, “where are you, Mom?”

“I’m here,” I heard her answer.

5K^(-1/2) C^(1/2)-L=0
5K^(1/2) C^(-1/2)+-4L=0
K+4C=16

This is part of a bigger problem on lagrangean functions - I need to know how I can solve for C, K and L. My main problem is that I do not know how to deal with the powers. I multiply the first equation by 4 then want to take the second to eliminate L but how do I deal with the powers?

What would the rules be regarding something like:

[C^(-2/3) B^(2/3)] / [C^(1/3) B^(-1/3)]

Powers confuse me! - I have an exam in this s*** tomorrow :(
