1. The problem statement, all variables and given/known data 2 particles travel towards each other at 10ms-1. Particle 1 has a mass of 10kg and particle 2 has a mass of 30kg. It is an inelastic collision. Find the magnitude of the Impulse of particle 1 and 2. 2. Relevant equations I=Ft=mv-mu m1u1+m2u2=(m1+m2)V 3. The attempt at a solution I'm able to calculate the final velocity of the two particles after the collision when they have joined. ((10×10)+(30×10))/(10+30)=10ms-1 but I cannot now calculate the impulse of any of the particles. For example for particle 1: mv-mu=(10×10)-(10×10)=0 Could anyone help?
