Gravitational fields

Once again, Good evening ladies and gentlemen.
Today's class was nice a quite, everybody was down listening carefuly the lesson.
The substitute teacher went over the Gravitational fields workheet questions 1-4.
Then we went over the accelerated motion II sheet questions 1-3, after he finished the question number 3 of the sheet, he subsequently said that we have to take the questions 4-5 and try them at home. To make things clear these two question weren't signed as a homework but all he said is that if you want to try go ahead, if you don't is all good.
For Ms. K the class wasn't so bad today, but we all missed you.
See you next week.
