Relative Velocity Swimmer Problem

AI Thread Summary
The discussion revolves around a swimmer's motion in a river with a current. The swimmer swims at 0.15 m/s toward the shore, while the river flows at 0.75 m/s. In 1.5 minutes, the swimmer is carried downstream, and the problem requires calculating both the distance moved downstream and the swimmer's velocity relative to an observer on the shore. The initial confusion about the use of relative velocity and vectors is resolved through clarification. The swimmer's understanding of the problem improves with the assistance provided.

Homework Statement



A swimmer maintains a speed of 0.15 m/s relative to the water when swimming directly toward the opposite shore of a straight river with a current that flows at 0.75 m/s.

(a) How far downstream is the swimmer carried in 1.5 minutes?

(b) What is the velocity of the swimmer relative to an observer on shore?


Homework Equations



I'm not sure, sorry.

The Attempt at a Solution




I know this involves relative velocity and maybe vectors, but I am unsure. Please help.

Thank you very much.

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 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
