Hi ZapperZ, I'm not ask to do ma work, my question is how can I find the good subject to start doing my physics project...thank you Hi danger, thank you My regard

Hi Danger, I'm trying to accomplish a physics project, and my subject is torque . Thees is the subject I have to work with it. I'm a college student ,and I live on Mississippi state (U.S.A). My subject not about the mechanics ,its about Torque= arm lever. force (T=RF). I need some Torque's...

Hi Danger, I have to do a project for my physic's professor, and my project about the torque, so I think I need some pectures, and a good subjects to make my project very good. I'm studying a College Physics . Danger, can you pease tell me here is the shop manual ?

Please if anyone can help me with my torque project. I need some subjects, and pecturs to finsh it. This is my first project to do, and I hope that well done. I look on the physic's site, but I afraid of any matter appropriately chosen. Thank you

you have to use some formulas to solve this problem, and check you book to find the formulas. Thank you

Hi Shooting star, you are correct. We solve the problem today. thank you so much.:smile:

Hi Shooting star, Howcom we use (-9.8) when the object go down? I'm a college student, I study college physics (seventh edition) so we use - 9.0 on chapter 3 when any object go down. Just check and tell me. Thank you

Hi , and thanks alot. Shooting star, I usa -9.8 becuase the box slope down. Mephisto thanks you for the link you gave me, and I think slove the problem like above on replay #11. than you

Hi Shooting star, sin(20)=.342 .3429(-9.8)=3.352 I don't know if I have correct answeer. This problem confused me so bad:confused:

Hello , shooting star and Silently loud. Thank you so much>>> both. I use cos, because the box sloped 20 degree horizontal. Silently I have no force how can I use F=ma?? I don't understand that. Thank you

Thank you Siracuse. because the box plane that is sloped 20 degree above the horizontal I think, I have to use cos. cos(20)=.940 .940(-9.8m/s)=-9.212 I don't know if that's correct. yes I learn all of Newton's laws.

thank you so much Siracuse. The formulas I have on my book a=f/m but how can i solve ?? and I have no force and mass. thank you

thank you

I need help with my problem! a box slides down a frictionless plane that is sloped 20 degree above the horizontal. Find the acceleration of the box. [COLOR="Red"]can anyone help me to solve this problem
