Stream Velocity Water

AI Thread Summary

To calculate the velocity of the water stream for the Archer fish, the problem involves determining the necessary launch speed to hit a target 2 meters away while maintaining a vertical drop of no more than 3 centimeters. The horizontal motion is analyzed using constant speed, while the vertical motion is influenced by gravity. The angle of launch is 30 degrees, which affects both the horizontal and vertical components of the velocity. By applying kinematic equations separately for the x and y directions, the required launch velocity can be derived. Accurate calculations will ensure the water stream reaches the target effectively within the specified vertical drop limit.

This problem seems to confuse me! If someone helps me with this problem I'll be so grateful!

An Archer fish shoots at a target 2m away, at an angle of 30 degrees above the horizontal. With what velocity must the water stream be launched if it is not to drop mote than 3cm vertically on its path to the target?

thanks

Deal with x- and y-directions separately.
Hint: x-speed is constant.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...

Thread 'Struggle to understand the concept of the 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...
