The momentum of the t-shirt will be its initial momentum (p0=0)(p0=0) plus its change in momentum due to the applied impulse: pf=p0+∫t=tLt=0F(t)dtpf=p0+∫t=0t=tLF(t)dt. By applying the given time dependent function for F(t)F(t) and performing the integration, which of the following is the correct expression for pfpf?
