Please describe step by step for each part

Your friend and you playing catch in a frozen parking lot outside a football stadium and you are standing on an ice patch; there is negligible friction between your feet and the ice. A friend throws you a 0.64 kg ball that is traveling horizontally at 11.9 m/s. Your mass is 70 kg. (a) If you catch the ball, with what speed do you and the ball move afterward? (i) Draw a diagram representing the motion, before and after (3 points) (ii) Define a coordinate system and show it in your sketch (2 points) (iii) Write the equations that apply (2 points) (iv) Solve your equations (5 points) (b) If the ball hits you and bounces off your chest, so afterward it is moving horizontally at 8 m/s in the opposite direction, what is your speed after the collision? (i) Draw a diagram representing the motion, before and after (3 points) (ii) Define a coordinate system and show it in your sketch (2 points) (iii) Write the equations that apply (2 points) (iv) Solve your equations (6 points)
