Answer:

(a) Inertia is the tendency of a body to remain in fact of motion or remain static until and unless an external force acts on the body and since it depends on mass of body hence M1:  M2 = 1:1 .

(b) The momentum of a body is also called as mass that is in motion if a body has mass and is moving it will definitely have momentum so M1V:M2V ⇒ 1:3 .

(c) Force on a body is also defined as Momentum per unit time hence, M1V/T : M2V/T = 1:3.

Answer:

Explanation:

(a) Since inertia is a measure of mass which is same for both bodies, so the ratio of inertia for two bodies will be  

1  ; 1

​  

(b) Momentum

P=m×v

P1  = m × v = mv

P2  = m × 3v = 3mv

P2  / P1  =  3mv  / mv

​=  3  / 1

​  

(c) Force

F×T=Momentum

F=
