Hi can someone please help me with these multiple choice question. My answers are wrong. I just need the correct answer with a short explanation on why the answer is correct. Thanks in advance!

A moving curling stone, a, collides head on with a stationaryr stone, B. Both stones are of identical mass. If friction is negligible during tis linear collision, 6) stone A will slow down 0 after the collision, the momentum of stone B will be less than that of stone A 0 both stones will come to rest shortly after the collision 0 after the collision, the kinetic energyr of stone B will be less than that of stone A 0 after the collision, stone A will have a speed of zero When you catch a fast moving baseball, your hand hurls less if you move it in the direction of the ball because 0 the ball changes momentum more slowly O the force applied is smaller 0 you decrease the impulse required to stop the ball 0 two of AB and C allofA,BandC Question 7 0.25 / 1 point Without knowing any other information that is given in the diagram, which deductions could be true? The eastbound car was travelling faster The northbound car was lighter Both cars had the same speed two of A, B and C all of A, B and CQuestion 1 0 / 1 point A 5.0 kg cat travelling at 1.3 m/s [ has a momentum of 6.5 m/s [E] 0 6.5 m/s [W] 3.8 m/s [E] 3.8 m/s [W] none of the above Question 2 0 / 1 point A person jumps from an airplane and reaches terminal velocity. Which of the following is true. The momentum of the jumper is constant because there is no external net force. The momentum of the person-Earth system is not conserved because of ir friction. when the chute is opened, the force disrupts the conservation of momentum of the person-Earth system. two of A, B and C are correct O all of A, B and C is correct
