End of Year Survey

Students:
I would like to thank-you for being patient this year.  This is not always the easiest job.  If I yelled at you pushed you made you work harder than you wanted, its because I want you to be the best you you can be, that comes from personal sacrifice.

Nothing worth doing, having or learning in this life comes free or easy!  Think back to a moment that you felt accomplished.  Why did you feel that way?  You should be able to think back a determine why. I wish you all the best and want nothing more than for you to be productive and happy in your life.  If this was not a good experience for you ask yourself did you do anything to make it better?

Snow day...

Mr. Crane shovels his 24ftX125ft driveway the snow is 10 in deep.  He throws the snow 4ft in the air before it comes to rest 3ft away.  How much work did he do on the snow?
Answer:0joules  work is defined as the measurable change of the KE of an object...  So could you determine which snow has more energy after the driveway was cleared? (NO)
A different question would be how much work did Mr. Crane do?
Wcrane=PE+KE of snow@ the top or bottom when it hits...




Do these guided problems below.  We are running tight to our schedule due to snow days.
