I'm sorry, I can't figure out what trig to do. I found the cross sectional area of the wire which is 3.8 x 10 ^-2 but I'm stuck on the trig and the difference in length. Can anybody explain how to do this so I will know for future reference?
P.s. thanks for your comment, it was really helpful
A stainless-steel orthodontic wire is applied to a tooth. The wire has an unstretched length of 3.1 cm and a diameter of 0.22 mm. If the wire is stretched 0.10 mm, find the magnitude and direction of the force on the tooth. Disregard the width of the tooth, and assume that Young's modulus for...
By the way, there is a figure provided with the question. There is a table that is 2.00 m off the ground with a slope on top of the table that is 2.50 m high with m1 at the top of the slope and m2 at the bottom of the slope. And x is on the ground out from the table.
Sorry guys for not showing my original effort. It was late. I tried finding vf with this equation: mgh + 1/2mv^2 = mgh + 1/2mv^2 and it seems like no matter what numbers I plug in I can't come up with the correct answer. I will try ya'll suggestions to see if I can do something differently...
Okay I have been working on this problem forever and I don't know what else to try. Can anyone help me?...
A 0.005-kg block is released from rest at the top of a frictionless track 2.50 m above the top of a table. It then collides elastically with a 1.00-kg object that is initially at rest on...
