Trajectory (Quick Question) -- where would it be maximum speed?

AI Thread Summary
The discussion centers on determining where maximum speed occurs in a given trajectory. It is clarified that at the midpoint of the trajectory, the velocity is not zero, contradicting the initial assumption. The maximum speed does not occur at point B, as that would imply zero acceleration, which is not the case. The conversation highlights the importance of understanding energy conservation and projectile motion equations in analyzing trajectories. Ultimately, the original poster resolves their confusion and acknowledges the clarification provided.

Hey so if we have a trajectory like this, where would it be maximum speed?

From what I understand, at the midpoint, v = 0 right? So would the maximum speed be in between the bottom (initial) and the centre of the trajectory (peak), represented by B in this photo.

I haven't done questions related to these in a while so I was just curious to know if I remember this or not.

Thanks :)

Use the template and check with the relevant equations under 2.

What do you expect ? You give no clue you know about energy conservation, projectile trajectory equations, or anything else related.

At C, the thing is clearly moving to the right, so: No, v is not 0.
If the speed would be at a maximum at B, that would mean acceleration 0 at that point. There is no argument for that, so: No, it's not in between.

You're welcome.

Hey, sorry about that, it was just a random question I found haha. I figured it out though, thanks :)
 

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 '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}...
