I need help with these two question please and thank you..

Please I want the hand writing to be very clear and easy to understand..

Exit Card Consider a collision in one dimension that involves two objects of masses 4.5 kg and 6.2 kg. The larger mass is initially at rest, and the smaller mass has an initial velocity of 16 m/s [E]. The final velocity of the larger object is 10.0 m/s [E]. Calculate the final velocity of the smaller object after the collision. Two objects of masses m and 3m undergo a collision in one dimension. The lighter object is moving at three times the speed of the heavier object. Describe what happens to their speeds after the collision. Explain your reasoning. Assume that the lighter mass is moving to the right
