Type 2 Projectiles TEST TOMMOROW

AI Thread Summary
A user sought help with a Type 2 projectile problem involving a gymnast's flip, needing to find the initial velocity and maximum height given a horizontal range and launch angle. They were initially confused about the components of initial velocity, specifically Vox and Voy. After some discussion, they recalled the range formula, which helped them solve the problem independently. The user expressed gratitude for the assistance and indicated that they no longer needed help. The thread concluded with a request for deletion as the issue was resolved.

okay i know how do do type one and type 3 projectiles but there is this certain kind of type 2 that i can't figure out. if the problem gives me a initial velocity and an angle of 30 degrees i am okay. BUT for this kind i don't know what to do:

"A gymnast becomes a projectile by doing a flip that gives here a horizontal range of 1.80 neters. If she took off at an angle of 60.0 degrees, determine:
1. initial velocity
2. the maximum height that she attains

PLEASE HELP ME
i have a test tommorow and got to figure this out. Any help would be appreciated.incase your wondering i know a few formulas like y =x tan(theta) - gx^2/ 2vi^2cos^2 (theta), also vf^2=vi^2 +2ax, and all the derivitives, I just don't have any clue on how to do this one.

i don't know what voy and vox means, i guess i haven't learned that yet, so how can i do it without knowledge of that.

If you set up an xy coordinate system, then Vox = Vo * cos(theta), and Voy = Vo * sin(theta) are the components of the initial velocity Vo along the x and y axis, respectively.
 
oh i figured it out one my own. I competely forgot about the formula:
Range = Vi^2 sin2(theta)/g

Well thanks for trying to help me i appreciate it. Now that i got this one of the mods can delete this thread.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
