Object A has a mass m and a speed v, object B has a mass m/2 and a speed 4v, and object C has a mass 3m and a speed v/3. Rank the objects according to the magnitude of their momentum.

Respuesta :

The rank is : [tex]P_B>P_A=P_C[/tex] .

We need to rank the objects according to the magnitude of their momentum.

We know momentum ,[tex]P = m\times v[/tex]{ here m is mass and v is velocity }

Momentum of object A , [tex]P_A = m v.[/tex]

Momentum of object B , [tex]P_B= \dfrac{m}{2}\times4v=2\ mv.[/tex]

Momentum of object C  , [tex]P_C= 3m\times\dfrac{v}{3}=mv.[/tex]

Now, we can rank them in order of  their magnitude of momentum .

[tex]P_B>P_A=P_C[/tex].

Hence, this is the required solution.
