Answer:
a) Yes, the mechanical energy of the system is conserved because they were no friction in the system.
b) Yes, the momentum of the system is conserved because the two car continued to move after collision and without friction.
c) No, the mechanical energy of the system is not conserved because the car is gaining speed due to gravitational force acting on the car as it roll down the hump.
d) No, the momentum of this system is not conserved because the car gains speed as it moves down, which changes the momentum of the car.
e) No, mechanical energy of the system is not conserved because the car is slowing down, that means frictional force is acting the oppose the motion of the car.
f) No, momentum of the system is not conserved because the velocity of the car has reduced after collision, which will cause the momentum of the system to change
