Physics 221 Summer 2012 HOMEWORK #3 Due Monday July 2‚ 2012 1 James Bond (90 kg)‚ outfitted with perfectly matching skis and skiware‚ is at the top of a steep slope that a secret spy like him can easily handle. He lets himself go from rest and smoothly slides down the h = 15 m high hill. A big parking lot lies at the bottom of the hill.

These are fair reasons to assign assignments‚ because they teach you new abilities and let you practice certain skills. With good reasons‚ there are unfair reasons as well. Teachers who have nothing better to do

Why do teachers assign homework to students during holidays? Is it because that the teachers feel that students are supposed to have more time to do homework as they do not have to attend school? I feel that homework are assigned to students so that they will not lose touch with the subject when school reopens. As some students take up to 10 subjects‚ their homework load is sure heavy. Although students do not have to attend classes during holidays‚ most of them prefer not to have holidays as their

motive‚ but who needs one? There are 10‚000 abandoned houses here and some still hold the remnants of their previous owners. What can a politician do for a town so messed up that thousands of abandoned houses are simply part of the scenery‚ where a serial killer can dump bodies at random without the fear of being caught? The answer is nothing‚ and they know it but will never say it. There have been plans- some of them good- but none of them effective enough to save a lost cause. As long as the city

common emotion to students regarding the distaste of homework‚ but legions of teachers know better because they recognize the importance of homework in the success of students in school and outside of school. I completely disagree with the statement that homework should be abolished. School without homework is not an image I can fathom. There are many reasons why homework should not be abolished as it is greatly beneficial towards the student. Homework improves the stability of the student in school allowing

I decided to do my project on the amount of homework students receive and how it is affecting their interpersonal relationships. Most of us have siblings‚ relatives or kids in grade school and can relate to this issue. We can all agree that they generally receive too much homework and it is causing them a lot of stress. Homework can be both good and bad. Some homework help reinforce the material already covered in class room while others are just worksheets and drill work. The truth is that students
