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 th
borishaifa [10]
<h2>The rank is : P_B>P_A=P_C .</h2>

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

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

Momentum of object A , P_A = m v.

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

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

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

P_B>P_A=P_C.

Hence, this is the required solution.

Answer:

F_a_v_g=7093333.33N*s

Explanation:

The impulse or average force in classical mechanics is the variation in the linear momentum that a physical object experiences in a closed system. It is defined by the following equation:

F_a_v_g=m*\frac{\Delta v}{\Delta t}=m*\frac{v_2-v_1}{t_2-t_1}

Where:

m=mass\hspace{3}of\hspace{3}the\hspace{3}object

v_2=final\hspace{3}velocity\hspace{3}of\hspace{3}the\hspace{3}object\hspace{3}at\hspace{3}the\hspace{3}end\hspace{3}of\hspace{3}the\hspace{3}time\hspace{3}interval

v_1=initial\hspace{3}velocity\hspace{3}of\hspace{3}the\hspace{3}object\hspace{3}when\hspace{3}the\hspace{3}time\hspace{3}interval\hspace{3}begins.

t_2=final\hspace{3}time

t_1=initial\hspace{3}time

Asumming v1=0 and t1=0:

F_a_v_g=m* \frac{v_2}{t_2} =(24.7)*\frac{784}{2.73*10^{*3} } =7093333.333N*s
