Particle A with mass m = 1.0 kg travelling at a speed v0 = 10 m/s in the +x direction collides with particle B of mass m = 1.0 kg at rest. After the collision particle A continues on in the same direction (+x) with a speed vA and particle B flies off with speed vB also in the +x direction. An amount of heat H = 9 J is produced in the collision due to friction. (Note that we made the masses of the two particles equal, so that should help with the algebra!) (A) Is this a perfectly elastic collision, a partially inelastic collision, or a perfectly inelastic collision? Explain your reasoning. (B) Use conservation of momentum to find an expression for vB. (C) Taking into account the heat H produced, then energy is conserved. Use energy conservation to find an expression for vB^2 . (D) Use your answer from part (B) in part (C) to solve for the final speed of particle A. Give a numerical answer in m/s
