Calculating Velocity for Cannon Ball with Wind Velocity

AI Thread Summary
To calculate the velocity needed for a cannonball to reach a target at a distance d with a launch angle of 45°, one must consider the effects of horizontal wind velocity, which can either assist or hinder the projectile. The absence of air resistance simplifies the calculations, allowing for a straightforward function to be derived for both scenarios of wind direction. The discussion emphasizes the importance of showing the work behind the calculations to facilitate assistance. Additionally, the user intends to implement this function in a Delphi game project. Clear guidelines for participation are referenced to ensure proper contributions.

Hmm, i have this cenario, there is a cannon and it's target, separated by a distance d, not necessaraly in the same heigh. what i need is a function that gives the velocity needed for the cannon ball reaches the target.

PS: consider the angle 45°, there is wind velocity, but not air resistance. The wind velocity is only horizontal, in favour or against the launch, I'd like a function for each of these two wind velocity possibilities.

Thanks in advance.

i have to implemet this function into a game project made in delphi =/

is that what you need? I'm not sure if i got what you wanted... I thought you were guessing it was for homework or anything...
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this 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...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
