AI Thread Summary
To calculate the velocity of a stunt car driven on a flat train car relative to Earth, you would add the speed of the stunt car to the speed of the train if both are moving in the same direction. This approach is similar to walking on a moving sidewalk, where your speed is combined with the sidewalk's speed. If the stunt car is moving toward the train's engine, the direction of the velocities must be considered. Understanding relative motion is crucial in physics, especially in velocity calculations. This concept is essential for solving similar problems in the future.

A stunt car is driven along a flat train car. The stunt car is moving toward the engine of the train. How would you calculate the velocity of the stunt car relative to earth?

Im in physics 11 and we are almost done our velocity chapter and this question was on our review.

Why not just add the car speed to the train speed if they are in the same direction (like walking on a moving sidewalk)?
 
ooh okay thanks, makes sense
 

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...
