- There is a particle in a system.The mass of this particle is M=0.5 kg. The initial and final velocity are V0=2i , Vf=2j (i,j denote the unit vector in x, y axes)
Question: 1) The initial and final momentum; 2) The impulse exerts on this particle
I know that: p=mv so v=(2+2)/2 = 2 Then p= 0.5×2 = 1 now how to get initial and final momentum
Another way: P initial = Mass × V initial = 1 , P final = Mass × V final = 1 Is this way true?
And I couldn't get the impulse!
