    Projectile Range
AI Thread Summary
The discussion centers on solving a projectile motion problem where the launch point is higher than the target point. The user has provided specific values: target distance (d) of 30 meters, launch velocity (v) of 22 m/s, gravitational acceleration (g) of 9.8 m/s², and launch height (y0) of 2 meters. The main goal is to determine the launch angle (theta) for the projectile. The user has attempted to solve the equation but has not succeeded and is seeking assistance. Clarification on the equation and methods to find the angle is requested.

Homework Statement


Hi to all guys i am not good in physics and trigonometric I tried to do a projectile system.My launch point is higher than target point.I know the velocity v, target_distance d, gravity g,Launch_height_y y0.I added a image that shows the equation.I tried my own but solved the equation.Please some one help me

d = 30,v = 22, g = 9.8 ,y0 = 2

In this problem, which quantity you want to find out?
 
i want to find out the angle(theata)
 

Thread 'Rolling without slipping on a curved surface'

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 .

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...
