Can you guys help me with my Physics homework? I don't know how to do it because I can't learn from my teacher. Plz halp.
1.) Jimmy decides to punch the teacher. The teacher's mass is 85 kg. When the teacher sees the punch coming, he backs up at a speed of .60 m/s. After the punch lands, he's moving back at a speed of 1.82 m/s. If the contact time of the fist to the body was 0.075 seconds, what average force did the punch have?
2.) Sammy is on tricycle A, combined mass 65 kg, and Chynna is on tricycle B, combined mass 80 kg. They are initially at rest, but they push off each other. What is Sammy's speed immediately after the push if if Chynna's is 4.2 m/s?

I know I said to wait, but give it a bump evey two hours or so. It has been three hours, no one replied and I feel responsible, have a free bump.
