A 2kg block initially hangs at rest at the end of two 1 meter strings of negligible mass. A 0.003 kg bullet, moving horizontally with a speed of 1000 m/s, strikes the block and becomes embedded in it. After the collision, the bullet/block combination swings upward, but does not rotate.

a. Calculate the speed v of the bullet/block combination just after the collision.
b. Calculate the ratio of the initial kinetic energy of the bullet to the kinetic energy of the bullet/block combination immediately after the collision.
c. Calculate the maximum vertical height above the initial rest position reached by the bullet/block combination.

First off I would like to say this is a greatprogram, I went out and got a Ti-89 titanium just so I could have your program for physics. I have been playing with it doing some problems and it works great. So what are the questions I have well here is a multiple part question I was asked to do last week but I am trying to figure out how to do all the steps on your program. I have been trying to find where I can calculate the thermal energy, potential energy etc...

Thank you for your time

Tom- I just wanted to let you know, it was the difference between an “A” and a “C” for me. The product worked well and I was extremely pleased to post not just an “A” on the final, but an “A” for the semester. With your help, I’ll take another stab at Calc II next spring, but for now, I’m on Cloud 9. Thanks again and Merry Christmas! -Darrin

Tom- As good as your every step calculus programs, thank you -Kevin

Tom, thanks for the quick reply and help. I can’t explain to you how much I love this program and your customer service was greatly appreciated. -Jared
