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.
 
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 '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}...
