Question

A shell of mass m and speed v explodes into two identical fragments. If the shell was moving horizontally (the positive x direction) with respect to Earth, and one of the fragments is subsequently moving vertically with speed v, find the velocity ‘ of the other fragment immediately following the explosion. (Use the following as necessary: v.)

    Answer:

    The velocity of the other fragment immediately following the explosion is v .

    Explanation:

    Given :

    Mass of original shell , m .

    Velocity of shell , + v .

    Now , the particle explodes into two half parts , i.e  \dfrac{m}{2} .

    Since , no eternal force is applied in the particle .

    Therefore , its momentum will be conserved .

    So , Final momentum = Initial momentum

    mv=\dfrac{mv}{2}+\dfrac{mu}{2}\\\\u=v

    The velocity of the other fragment immediately following the explosion is v .
