The position (x-time () graph for a particle of mass 1 kg moving along x axis is shown in figureFind impulse on particle at t = 4 s.x (m)20A hall of

Answer»

Actually, thwre is no figure attached,

But I have solved a same problem with the diagram

So I am answering this based on that diagram.

Impulse = Pf- Pi(where P = momentum = mv)Pi= m*(d/t) = 1*(20/4) = 5 kg m/sPf= m*(d/t) = 1*(-20/4) = -5 kg m/s

I = Pf- Pi= -5 -5 = -10 kg m/s
