Today we started off class with daily question from our homework last night. This daily question was collected. The first question was how can a boxer minimize the damage to his jaw when hit by a fist with large momentum. The second question is if a 1000 kg car is going 10 m/s how long must an engine supply a force of 30 N until the car reaches 24 m/s. After handing in the daily question, we went over yesterdays entire homework. Then we were handed another daily question that was not graded. This worksheet consisted of 4 problems about momentum and impulse. After going over it as a class, we took a couple notes and were handed another momentum and impulse worksheet that we had 15 minutes to complete. Once completed, we spent the rest of the class period going over it.
