A ball is thrown at a 40 degree angle above the horizontal, across level ground. It is released from a height of 2 meters above the ground with the speed of 18 meters per second. What is the height above the ground that the ball reaches?

Hello, everyone. Tom from everystepphysics.com and everystepcalculus.com. We’re gonna do a physics problem of a ball being thrown. So I’m going to read it to you. It’s off a test. A ball is thrown at a 40 degree angle above the horizontal, across level ground. It is released from a height of 2 meters above the ground with the speed of 18 meters per second. What is the height above the ground that the ball reaches? It gives you 5 answers. To choose. Multiple choice. So, let’s do it. Physics to get to my menu into the entry line here. And we’re going to scroll down to You can go down the menu quick but this is a long menu so a lot of things in here so you’re going to press second and the cursor second cursor to go down page by page. I did that and went down here we’re going to choose ball thrown. An object launched with angle and initial velocity, it doesn’t make a difference whether it’s a ball or a tennis ball or a rock. Whatever. It’s the same formula’s.So you have to kinda practice with my programs, here to get used how they work. And practice them more than Physics, actually. And I give you the answer here or questions whether it’s aboveground or ground level. It makes a difference. So we’re gonna enter the initial height that they give you.You have to press Alpha before you enter anything into these entry lines, here. Alpha 2 and I always give you choices in case they try to trick you with inches or feet or conversions. We’re going to choose number 2 which is meters. And then the initial velocity is Alpha 18 meters per second, number four. Enter the angle. Alpha 40 degrees. I always show you what you’ve entered so you can change it if you made a mistake. I say it’s okay.

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
