    Height Wedge
AI Thread Summary
The discussion centers on calculating the height of a frictionless wedge after a block is released from it. A 0.5 kg block is released from the top of the wedge and, upon leaving, has a velocity of 4 m/s to the right. To find the wedge's velocity after the block reaches the horizontal surface, participants suggest using the work-energy theorem or analyzing normal reaction forces in circular motion. The problem emphasizes the importance of showing calculations and thought processes. Ultimately, the height of the wedge is a key variable in determining the final velocity of the wedge.

A small block of mass .5kg is released form rest at the top of a curved-shaped frictionless wedge of mass 3 kg , which sits on a frictionless horizontal surfces. When the block leaves the wedge, its velocity is 4 m/s to the right. Find the velocity of the wedge after the block reaches the horizontal surface. What is the height of the wedge?:biggrin:

You should really show some of your working / thoughts. Hint: Use circular motion and think about normal reaction forces.
 
Alternatively, you can use the work-energy theorem.
 
The work energy theorm is probably simpler.

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...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
