AI Thread Summary
The discussion focuses on calculating the launch angle of a lob pass thrown at an initial speed of 21.5 m/s with a flight time of 2.97 seconds. It also addresses finding the initial speed and time of flight for a bullet pass launched at a 25-degree angle. Participants emphasize the use of kinematic equations of motion to solve these problems. The conversation highlights the importance of understanding these equations for accurate calculations. Overall, the thread aims to clarify the application of physics principles in sports-related scenarios.

the lob pass is thrown with an initial speed of 21.5 m/s and its time of flight is 2.97s. What is its launch angle?

The bullet pass is thrown with a launch angle of 25 degrees. What is the initial speed of this pass? What is the time of fight of the bullet pass?

what formulas and how is this worked out?

Welcome to the PF. You use the kinematic equations of motion, which you no doubt are studying now. What are those equations? How would you use them to start to solve these problems?
 

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...
