Ok so i understand what you mean about vx=-vy, so with this being said i should be able to take dx/t = the rearranged formula for dy=vit+1/2at2, my only issue is that it doesn't work out. I am assuming that I am rearranging something wrong or my logic is flawed.

Ok well ill give it a shot tomorrow and post back on here if I've gotten it or not.

ok that makes some sense to me, so the y(t) = ..., x(t) = ... gneill was talking about refers to dx =...and dy =... equations? such as dy = vi • t + 0.5 • a • t2 And i am assuming that the "nastier equation" is referring to the formula that i create to cancel out a variable that i don't have...

God i feel like such an idiot, I've got you helping me and I am still confused. Ok so these are the equations I've got, d = vo • t + 0.5 • a • t2 vf = vo + a • t vf2 = vo 2 + 2 • a • d d = (vo + vf)/ 2 • t and the way you put it in your post ("y(t) = ..., x(t) = ...") confuses me as i don't...

Well i guess this is where I am supposed to be...im Ariesspear and I am a 17 year old in Canada currently finishing up grade 12 with hopes of going into mechanical engineering.

Ive used the Vx=Vcosθ and Vy=Vsinθ ( where θ = 45) yet all i get from both of those is 0.7071V. You mention in respect to time and i assume that i am misinterpreting what you mean to convey, as there is no time as of right now in my equations and problem.

Im not sure if i understand. I know that you can find the components (such as Vx and Vy) for an angled velocity by using the equations Vx=Vcosθ and Vy=Vsinθ. I am doing this for an advanced physics assignment at school and I am the only one doing it and I've been running over all of my notes and...

I set up a triangle which has the 10.0 meter fence as the y-axis and the 8.0 meter distance as the x-axis and the balls path is the hypotenuse in between. I do have those distances but without any form of time i still can't calculate anything from that triangle i don't think. And the Vy,f is the...

Homework Statement A fly ball just clears a 10.0 meter fence on the way down at a 45 degree angle, and strikes the ground 8.0 meters beyond the fence. Calculate the speed of the ball when it left his bat (at ground level). since it lands at ground level dy=0 a=9.81m/s2 since it is the only...
