Some PHYSICS Problems.
Okay, let me give a little introduction. My 11th grade Physics teacher gave us a 6 page take home test and said we can use collaboration from book, internet help, or parents to complete the test. (I believe this is because he can't teach it). And since my teacher knows little about teaching a subject nobdy in the class understands the higher level problems. I am here for some help. I have about 10 on this test that I simply can't find the answer to but I will start off on here with 3 of the easier ones. If you can help me farther on this I would owe you greatly, in that case Email me: id43rd1@earthlink.net or talk to me on Aim: xSrewop27x to talk about the rest of the problems.
1) An object is on a frictionless inclined plane. The plane is inclined at an angle of 30degrees with the horizontal. What is the objects accelerations? (prly easiest, but confused me)
2)A lantern of mass (m) is suspended by a string that is joined to two other strings. What is the Tension in each string if they make equal angles of 35degrees from the support beam?
3)A child sits on a sled at rest on a snow-covered hill making an angle with the horizontal. If the coeffient of friction is .10, what is the maximum angle at which the sled remains at rest? Approximate the hill as an inclined plane.
(I HAVE PICTURES to go along wit hthe LAST 2. Email me or let me know if I should scan them for you!)
