AI Thread Summary
Launching a ball at a 90-degree angle maximizes air time due to the higher peak it reaches compared to other angles. This angle allows the ball to spend more time ascending and descending, resulting in a longer duration in the air. While 45 degrees is optimal for distance, it does not provide the same airtime. The "y component" of the velocity is greatest at 90 degrees, contributing to the extended airtime. Therefore, for maximum air time, launching a ball straight up is the most effective approach.

I was just wondering, let's say you launch a ball, what angle would give you the longest time in the air? I know that 45 degrees will make it go the farthest but is that also for longest time in the air?

Simply 90°. Why? Because the ball will go higher than a pitched ball with the same impulse. It will take longer getting at its higher peak than a ball pitched with the same impulse but with a different angle. Furthermore it has to go down... which also will take longer.
 
Oh I see thanks
 
Yeah, but even more so, it will be because the "y component" of the velocity will be greatest at 90 degrees.

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...
