Tension of string when an impulse is applied

Click For Summary

Homework Help Overview

The problem involves two particles connected by strings, where one particle is struck horizontally, and the tension in the strings is to be determined. The context includes concepts of dynamics and impulse in a gravitational field.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the implications of the horizontal strike on the upper mass and its effect on the lower mass. Questions arise about the relationship between impulse and tension, and the movement of the lower mass is questioned. There is also consideration of the forces acting on the upper mass as it moves in a circular arc.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some guidance has been offered regarding the forces involved, but there is no explicit consensus on the mechanics of the situation or the calculations needed.

Contextual Notes

Participants note the complexity of the lower mass's movement and the need to consider the initial conditions after the impulse is applied. There are indications of urgency in the requests for help, suggesting constraints related to time or assignment deadlines.

Homework Statement


A particle A (mass m1) is suspended under ceiling by a light string of length L1. Another light string length L2 is connected to A at one end and connected to particle B(mass m2). They are stable under gravbity at first. Suddenly a horizontal strike is given to A and A has instanteous speed v. What is the tension of the 2 strings?


Homework Equations


mv=change of momentum= impluse?


The Attempt at a Solution


I think B does not move at all as the strike is to A.
But mv is impluse and tension is force. How to relate them?
I also don't know how to calculate the angle? help!

very urgent i have uploaded the question now help please!
 
is it due to the implusive tension?
 
Consider the fact that the upper mass, confined by the string l1, is forced to move in a circular arc. What must the net force on it be?
 
how about the lower mass does it move?thx
 
The movement over time of the lower mass is not simple.
In the first istant (while upper mass has already a speed of v) lower mass doesn't move.
Can you guess why ?

What about the chain ? Any news ?
