Hello, Everyone. Tom from everystephysics.com. Here’s a test problem. I’m gonna read for you. A cart is given an initial velocity of 5 meters per second and experiences a constant acceleration of 2 meters per second squared. What is the magnitude of the carts displacement during the first six seconds of it’s motion? I always want you to in these problems to circle what’s asked for. In this case displacement and I want you to write on the side of the program what’s given. Which is in this case initial velocity, acceleration, and time. So, let’s the do it. You have to put physics in here with the open/close parentheses to get my menu. We’re gonna scroll down to displacement because that’s what it’s asked for. And we’re gonna choose what’s given which is velocity, acceleration, and time. There’s a formula for it. You have to press Alpha before you enter anything in these entry lines. So the the initial velocity is Alpha five and meters per second. I do the conversions. Is acceleration given? Yes. Acceleration alpha 2. And the time is alpha 6. I always show you what you’ve entered. You can change it if you want. I say it’s okay. Here’s the answer: letter C

A rock is thrown straight down with an Initial Velocity a 14.5 meters per second, from a cliff. What is the rocks displacement after two seconds? Acceleration due to gravity is 9.8 meters per second squared.

Hello, Everyone. Tom from everystepphysics.com I’m going to read a test problem to you. A rock is thrown straight down with an Initial Velocity a 14.5 meters per second, from a cliff. What is the rocks displacement after two seconds? Acceleration due to gravity is 9.8 meters per second squared. So let’s get started. Physics to get my menu. Scroll down to Displacement because that’s what you’ve circled. And that’s what is asked for the problem. And we scroll to what’s given and in this case velocity. Initial velocity, time, and acceleration. There’s a formula. Write that on your paper. And you have to press Alpha before enter anything in here. So we have to press Alpha. Initial Velocity is 14.5 meters per second. Is acceleration given? It is but in case it wasn’t, I’m going to show you this, you can put 9.81 in there but if you didn’t, it’s assumed that you’re supposed to know that. So I’m going to choose number 2. It goes right away to time. Alpha is two seconds. And I always show you what you’ve entered so you can change it if you want. I say it’s okay. Here’s the answer: 48.6 And they have for their answer 49 when they here for their answer 49. You’d circle that one and get an A on this problem.

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
