Thank you both I figured it out, what i had to do was to use the components of v_0 to find it's magnitude: v_0^2=v_0^2sin^2(\theta)+v_0^2cos^2(\theta) from the equation of h it is clear that: v_0^2sin^2(\theta)=2gh Next i replaced sin(2\theta) in R equation by...

Hi every one Homework Statement If (R) is to be the horizontal range of a projectile and (h) its maximum height prove that the initial velocity is: [tex] \sqrt{(2g(h+\frac{R^2}{16h}))} [\tex] Homework Equations [tex]R=\frac{v_0^2 sin(2\theta)}{g}[\tex] [tex]h=\frac{v_0^2...

well i have studied them but i can't say that i have mastered them also there is one problem which is the way i studied them weren't very good you see in my country we don't actually "learn" rather we are more taught to memorize things we become like slow calculators we can give you the...

well i can cook some meals, iron a shirt but i don't know how to drive at all i always disliked driving car or even riding a bike but i guess you are right I am going to try to learn that but i won't worry about checks in my country we don't have banks and that kind of stuff the only banks that...

In math i studied (algebra, geometry, trigonometry , logarithm , graphs and linear models ,limits, derivatives and their applications ,integrals and their applications , and a bit of conic sections ,also a bit of complex numbers too but i forgot them) in physics ( classical mechanics ...

thanks great tips especially the one about communication yes i suck in it even when i speak my native language it is sometimes hard to understand me and that is probably because I am an introverted person. do you think Feynman's lectures are appropriate because some people say that they are...

Hi high school is finally over and now it is time to get ready for college but how?:confused: i have been searching the internet for a week now to find the answer for that but i haven't found it so if you can help me it would be very appreciated . Im interested in physics and want to become a...
