I have a couple of questions that I could use help in answering if anyone could lend me a hand it would be greatly appreciated.

900 kj is applied to 50g of aluminum, what is the specific heat?

Snowboarder traveling 14m/s jumps a ramp, what is the max height?

Pendulum length L & period T, the length increases to 2L, what is T?

5kg car collides head on with an identical car at rest, 1st car comes to a stop, what happens to the 2nd car?

I realize some of the questions seem vague, but this is how they appear on the test?
Any input will be helpful.
Thanks

Hi brute25! Welcome to PF! :smile:

hmm :rolleyes: … let's start with:

What have you tried? What equation do you think would help? :smile:
 
I'm not real sure.
I'm taking the texes exam to become a science teacher in texas and this question was on the test.
My strengths are in anatomy & biology.
Is there a goog website to look up the equation?
Thanks

ah … I think you need a good book which covers the whole of physics rather than a few websites to answer individual questions.

To be a Texas science teacher, you presumably need to know a lot more science than you do at present.

To deal with the questions you asked:

a] wikipedia "specific heat".
b] you ned to know formulas for uniform acceleration
c] wikipedia "pendulum"
d] momentum is conserved in all collisions

But this is a patchwork approach … not very appropriate for a big career step.

I suggest you start a thread in the Academic & Career Guidance forum (click https://www.physicsforums.com/forumdisplay.php?f=139"), where more people who can help will see it, and explain what Texas expects of you (and when), and what your personal history is, re physics and maths. :smile:
