Okayyy but I got used to using FBD then proceed to do equations. But my problem is I don't know if my FBD is right

Idk what you mean by that? Bcccc I don't want to be spoonfed too. What I mean by help is to guide me? I read the guidelines about posting homeworks I think I've followed them. Like what I said english is not my first language so can you pls go easy on me will you? Nonetheless I've done finish...

I got a and b last night. My answer for the magnitude is 18.2838 I got it from sqrt(14^2+11.76^2) I got 11.76 from Vf = Vo-gt<- (9.8)(1.2) soooo next is c,d,e,f.. any help?

Okay done reading. So can you guide me in the question?

I sort of understand free fall which lead to projectile motion right? Look. I'm not totally clueless about the question. But a help is all I need, I'm not asking for answers. I'm a type of person who understands lesson via examples. This is my first time encountering this type of Q but this...

But I'm sort of getting the idea of freefall. I will change a into g right? 9.8 m/s^2

Sooo okay S=(14)+1/2(9.8)(1.2)^2 Am I right? S=(14)+1/2(9.8)(-1.2)^2

I think you mean this? the 2nd equation I assume? or you mean this Vx = VoCosΘ Vy = VoSinΘ ??

Oh okay? I think it is up to down only so maybe the x-component will not change? Then my drawing is wrong if that;s the case

Well I think so. Yes. If I'm wrong, please tell me why, I would love to know. Thank you!

Homework Statement The magnitude of the velocity of a projectile when it is at its maximum height above ground level is 14 m/s. (a) What is the magnitude of the velocity of the projectile 1.2 s before it achieves its maximum height? (b) What is the magnitude of the velocity of the projectile...

Yeap I have no problem answering the problem until the quadratic.. So I tried using a calculator and the answer shows the 11.448.

I got 212.42=34.01(t) -1.35(t)^2 from the 3rd formula in my OP

212.42=34.01(t)-1.35(t)^2 I just use quadraic 13.744 and 11.45 I don't know what you are saying but I shown my work already in the solution area I completed the template.

Y Hey that's right sir I have bad habits not posting units in exams (which lead to deduction lol) I tried the other method and I got 13.7445s and I add it to 3.47s = 17.21s but it is wrong and can you please explain where did I get wrong but my (b) is right (271.42m) EDIT: I kinda have bad...
