Suggestions for projectile motion

AI Thread Summary
The discussion focuses on advanced applications of projectile motion equations, with suggestions for complex scenarios such as artillery targeting at different altitudes and calculating optimal launch angles on slopes. Landing a spaceship on Earth is highlighted as a particularly challenging example due to varying gravitational effects and the need to account for drag and lift in non-linear motion. The complexities of using polar or spherical coordinates for high-speed landings are emphasized. Additionally, modeling a football's trajectory while considering air drag is proposed as another advanced project. Overall, the conversation revolves around exploring sophisticated uses of projectile motion in various contexts.

Hey everyone,

I have to derive and use equations for a projectile motion prject. I already know how to derive the equations but I need help in coming up with a situation in which I can use the equations. I want a really advanced use of projectile motion.

I have some ideas like in artilleries and so on in the millitary but i wanted something that is more advanced like landing a spaceship on Earth (if it is considered a projectile). So all i am asking is for a suggestion for what you think is the most advance use of the projectile motion equations.

Thank You

Start with hitting a target at a different altitude. That's pretty tough.

How about calculating the optimal angle for launching a projectile up a slope?

Landing a spaceship involves dealing with changes in gravity with altitude which is pretty tough.
 
Landing a spacecraft will be a tough project. With the speeds involved, you will need to do the entire thing in polar (or spherical) coordinates. Including drag will make it even more difficult still. You'll need to include lift and drag effects which are non-linear with altitude, and all motion is elliptical - not parabolic.

Have you studied rigid body rotational dynamics? Try modeling a football with air drag.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
