Calculating Change in Velocity of Ball from E to S

AI Thread Summary
To calculate the change in velocity of a ball moving from 1.0 m/s East to 1.0 m/s South, the initial and final velocities must be treated as vectors. The change in velocity is determined by subtracting the initial velocity vector from the final velocity vector. This results in a vector pointing southwest, with a magnitude calculated using the Pythagorean theorem, yielding approximately 1.4 m/s. The discussion emphasizes understanding vector subtraction and the resultant direction of the change in velocity. The final answer indicates that the change in velocity points southwest.

Homework Statement


The initial velocity of a ball is 1.0 m/s East (E). The final velocity is 1.0 m/s South (S). The change in the velocity of the ball is?


Homework Equations



(x^2+y^2)^.5

The Attempt at a Solution


would it simply be 1.4 southeast?

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...
