Finding Distance of Two Runners with Velocity and Acceleration | Help Needed

AI Thread Summary
Runner A starts 6.0 km west of a flagpole and moves east at 9.0 km/h, while Runner B begins 5.0 km east of the flagpole and runs west at 8.0 km/h. To find the distance between them when their paths cross, equations for each runner's position over time are needed. By solving for the time at which their positions are equal, one can determine the distance from the flagpole. This method can also be applied to similar problems involving velocity and acceleration.

Runner A is initially 6.0 km west of a flagpole and is running with a constant velocity of 9.0 km/h due east. Runner B is initially 5.0 km east of the flagpole and is running with a constant velocity of 8.0 km/h due west. What will be the distance of the two runners from the flagpole when their paths cross?

Write an equation for each runner, solve for time, then plug time into one of the equations to get distance. Use the same method for the other problem you posted.
 

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...
