Tension of string when an impulse is applied

[jessicaw]

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!

 

[jessicaw]

is it due to the implusive tension?

 

[RoyalCat]

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?

 

[jessicaw]

how about the lower mass does it move?thx

 

[Quinzio]

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 ?
