Ok, thanks for the reply. If that's the case, does that make the rest of the equation:
(-x^5) / 12 + (5x^4)/6 - [(103x^3)/12) / 3] + [(23x^2)/3) /2 ]
Thanks again.
I am taking an Architectural Geometry class, and have only had Precal. We just started antiderivatives (I understand regular derivatives), and had a question:
I have to find the antiderivative of
(-5/12 x^4) + (10/3 x^3) - (103/12 x^2) + (23/3 x)
I think I use the power rule for...
Thanks for the reply...ok the spec. heat of the lead bullet is 128 kg/J*C
how do I convert the Kinetic Energy into Thermal?
So far I have:
Q = (m)(c)(change in temp)
? = (.0042)(128)(x)
I don't know how to find Q, so then I can solve for x.
Thanks.
A 4.2 g lead bullet moving at 260 m/s strikes a steel plate and stops. If all its kinetic energy is converted to thermal energy and none leaves the bullet, what is its temperature change?

Doc Al,
I called a classmate, and he had used the same formula I did...and got the correct answer. After walking through my steps with him, I found that messed up here:
cp water, given

(4186) (.630) (x-90) = (4186) (.445) (x-22)
774.41x = 196365.26
It should have been 90-x...

Thanks again for sticking with me, but I am still pretty confused. I'll just ask my teacher to walk me through the steps to see where I messed up. Thanks though.
Thanks for the reply, but I am still unsure as what to do:

Just a little more help please...
Thanks for the reply, I was eventually able to work through it and get my answer! It turns out that I had the formula wrong.

This is similar to the second question I had, but they want the centripetal accel.
