please show steps and calculations. Circle answer please. I am not sure how to solve homework.

Problem 3(25pts): Blocks A and B are moving toward each other. A has a mass of 20 kg and a velocity of 50 m's, while B has a mass of 40 ka and a velocity of -25 m/s. They suffer a completely inclastic collision. A. (5pts) Draw a picture of the situation. Make sure to include a coordinate system (label positive and negative directions). In the picture include an arrow above each cart showing the direction of the velocity. B. (10pts) What is the velocity of the of the carts after the collision. To get full credit you must show all your work. I am looking for the steps you took to solve the problem. C. (10pts) What is the kinetic energy lost during the collision?
