AI Thread Summary
To determine the launch angle for a stream of water hitting a beetle on a leaf 3 cm above the water surface, the initial speed is given as 2.3 m/s, and the vertical component of velocity (Vy) is zero at the moment of impact. The gravitational acceleration (Ay) is -9.8 m/s², and the vertical displacement (Dy) is 3 cm. The time of flight can be calculated using the equation Dy = 1/2(Ay)*Time², which allows for the determination of the time before impact. The horizontal component of velocity (Vx) can then be derived from the initial speed, enabling the calculation of the launch angle using trigonometric relationships. Overall, the problem involves applying kinematic equations to find the necessary angle for the water stream's trajectory.

A stream of water is shot with an initial speed of 2.3 m/s at a beetle on a leaf 3cm above the waters surface. If the fish aims in such a way that the stream of water is moving horizontally when it hits the beetle what is the launch angle.

Given:
Because the stream is moving horizontally then Vy = 0 m/s.
Ay = -9.8 m/s (gravity)
Displacement y (Dy) = 3 cm
Initial V = 2.3 m/s

How can i find the launch angle

Dy = Initial Vy * Time + 1/2(Ay)* Time*Time but don't know time or Vy

and i know nothing for x.

If the stream is moving horizontally, then it is at the peak of its jump. Vy = 0 at h = 3cm. You can use this to find the time.
 
but i am not given Vy i am givin Initial V which is the square root of Vy squared plus Vx squared. And i cannot derive either of those because i don't have an angle to work with.
 
You can find Vy because you know it is such that v_{y0}t = -\frac{1}{2}gt^2 [/tex], the moment it hits the leaf, all the upward velocity has been lost to gravitational pull.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
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...
