Re: Physics class homework help

Hi Folks,

It looks like a few folks are having trouble finding that final time.  Let me see if this helps.

So you've got distance and you've got time, right?  This allows you to figure out average velocity?  So, if the wagon was constantly accelerating, when was that average time reached?  Remember the ball and the ramp?  You figured out the average velocity using v=d/t, how did you take that average to find the final velocity?  We've also done this on quizzes.  Take a look at some of your old quizzes to see if you can find the answer.  

Let me know if you're still having trouble and I'll help more.

Good luck!

Hi folks,

I thought I had included this in the original email but apparently I didn't.  We pulled the wagon 3 meters.

By the way, be careful in your calculations.  If you use v=d/t that gives you the average velocity.  To calculate, acceleration, you need the velocity the person was going at the end of the 3 meters.  This is something we've had quiz questions on and we've done in one of the ramp and ball labs we did a while ago.  I'll leave you with that.  Feel free to email me if you need hints.

Good luck everyone!
