AI Thread Summary
In the relative motion problem, a person standing still by the road will appear to be moving west as the bus approaches. The correct interpretation is that the observer in the bus perceives the stationary person as moving in the opposite direction to the bus's motion. The options presented include incorrect assumptions about the person's speed relative to the bus. The discussion concludes with the consensus that option C is the most accurate choice. Understanding relative velocity is key to solving such motion problems effectively.

I'm wondering about this question:

You are in a bus moving at a constant velocity due east. Ahead of you, you see a person standing on the side of the road. How will the person appear to you as you get closer to him...

a. as he is standing still
b. as he is moving east at the same speed as the bus (this one is wrong for sure)
c. as he is moving west at the same speed as the bus (i think this is correct)
d. as he is moving west at a slower speed than the bus

Am i right in choosing C?

That problem seems oddly worded, but yeah C looks good.
 
thanks, appreciate it
 
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...
