Middle School Physics

Erika Said:

Please Momentum-Impulse physics problem Middle School?

We Answered:

m1v1 +m2v2=m1v'1+m2v'2

m1(4.75)+ 0= m1(2.60)+100(2.60)

m1(4.75-2.60)=100(2.60)
m1=120.93 kg

Can anyone help me think of a good middle school science project for physics?

We Answered:

American Scientific Surplus has a build your own motor kit that would be great idea. They also sell solar cells so you can do a project with those. You can use the motor kit to hook up blades and study a windmill, they have equipment for that as well. They also have a kit to build an electronic eye and a lot of other things (http://www.sciplus.com/).

I had a lot of good locations to search in this answer: http://answers.yahoo.com/question/index;…

People who know about middle school physics only!!!!!!!!?

We Answered:

The car was travelling at 75 x 60 kmph.
It took him 4.2 seconds to slow down.
Using that information you should be able to work out the answer.

I do not supply instant answers, but the guidelines as to how to work out the answer.

Need help with middle school physics (related to Hooke's law and elongation of spring and tension force)?

We Answered:

20N = 16 cm
10N = 14 cm
so extra 10N stretches 2 cm . take this off the 10N loaded spring gives no load and 12 cm
