Great lesson, helped me understand it more, thanks.

But I got a question, my problem is always about choosing the right equation because there are too many, but @ 3:14 in this video you said: "I can use my big five equations".

Can you mention these 5 equations please? I'll be grateful, thanks a lot!

@iHateMyLifeGr We have a video on our website. Youtube will not let me put the link here so go to the website listed in the description and look for Physics Lesson: Acceleration Equations Part1. I think it will help.

[commando1888]

how do you use the quadratic formula???which one is a or b or c???

[PhysicsEH]

@commando1888 d = V1t + 1/2 at^2 so for this one -40 = 100t - 4.9t2. You must rearrange it to be -4.9t^2 + 100t + 40 = 0 Which is like the form of the quadratic which is ax^2 + bx + c = 0 so a = -4.9, b = 100 and c=40. You need to look up the quadratic formula which will show you where to put a, b and c to calculate x (or t in this case). I can't write it here. I hope this helps.

Please quit your job and come to my school!!!

[Arphyn]

shit, better than my teacher! thanks a lot

Why is the initial vertical velocity 100m/s and not 0m/s?

[tiggs1792]

im in college physics and you explained the material better than my professor with a phd. thank you very much

[luikahei1]

thx 

[Devantium]

Y u no do the V2v??? i never know what it is

[mrtsunny]

ive been having trouble with projectiles at an angle. thanks for clearing this up!

[IaMtheChiTownCp3]

Thanks my physics doesn't explain like you

[Arie5009]

thanks
