MOMENTUM: COLLIDING PARTICLESParticle A with mass m= 1.0 kg travelling at a speed vo 10 m/s in the +x direction collides withparticle B of mass m= 1.0 kg at rest. After the collision particle A continues on in the samedirection (+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 inelasticcollision? Explain your reasoning.(B) How much negative work has gravity done as the train goes up the mountain?(C) What is the net work on the train by all the forces acting on the train?(D) What is the speed of the train after it has travelled the 1,000 m?

Since all the parts are not interlinked, solution for the first question is provided here.
