Estimate the velocity of each stone have just after the collision

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving the collision of two curling stones on ice. The original poster describes a scenario where stone A, moving at an initial velocity, collides with stationary stone B at an angle. The problem includes estimating the velocities of both stones after the collision and analyzing the kinetic energy loss, while also questioning the nature of the collision.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Some participants suggest using conservation of momentum in both the x and y directions to analyze the collision. Others express a need for more information and clarification on the concepts involved, particularly regarding momentum and its implications.

Discussion Status

The discussion is ongoing, with participants seeking further clarification and information. There is a mix of attempts to guide understanding of momentum and its role in the collision, while some express uncertainty about the concepts. No consensus has been reached, and various interpretations of the problem are being explored.

Contextual Notes

Participants note the lack of specific information regarding the mass of the stones and the nature of the collision, which are critical to solving the problem. There is an emphasis on the need for participants to engage with the material rather than receive direct answers.

Hi :smile: I really need a answer to this task. Hope anyone can help.

A curling stone ( named A ) gets on the ice with a unknown beginning velocity Vo
the stone moves along a straight line ( x-axis ) on the x-axis further ahead lies another
stone ( named B ) still. Stone A collides with stone B in a sloped hit/knock
Just before the hit stone A has a velocity of 2m/s. After the slope stone A moves
straight with a angle of 45 degree in proportion at/of the x axis. Equivalently for stone B is -30 degrees.

a ) Estimate the velocity of each stone have just after the collision

b) Estimate the loss of kinetic energy in this collision. A curling stone have mass 20kg. what kind of collision is this ?


The reason for the energy loss is that big is that ice-sludge came between the stones in the collision. We clean up and retake the attempt. Now we reckon that the push is approximate perfect elastic Stone A has the velocity of 2 m/s before the push/hit and 1,5m/s after. The direction of a form the angle 41,3 degree with the x-axis after the push/hit.

c) Find the velocity and direction of B after the stone is Pushed/released.

d ) Check that the push of the stone is approximated elastic, by calculate the x component

a) use conservation of momentum in the x and in the y direction.
 
Thanks. But can I get some moore information I am a noob :)
 
none ?

What further information do your require?

The formula and correct answer would been nice

Nope, we don't do that here. Your going to have to do some work yourself. What can you say about the total momentum before and after the collision?

Its less after the collition (velocity) ? Not sure what mometum means movement/direction or velocity ? But I am guessing its velocity

Heres a good elementary resource: http://www.glenbrook.k12.il.us/GBSSCI/PHYS/CLASS/momentum/u4l1a.html

But in a you don't know the mass
