1. The problem statement, all variables and given/known data Two objects are connected by a light string that passes over a frictionless pulley as shown in the figure below. m1 = 8.32 kg, m2 = 6.40 kg, and = 56°. When released from rest, m1 accelerates downward at 2.210 m/s2. For this to happen, the coefficient of kinetic friction must be [blank], and to even begin sliding in the first place the coefficient of static friction must be [greater than or less than] than [blank] . link to figure http://www.webassign.net/userimages/SerPSE8-5-p-030-phi.png?db=v4net&id=208569 2. Relevant equations F=ma Fk=μN 3. The attempt at a solution Ok here goes. I 'solved' this with great confidence, only getting wrong answers. Hopefully you guys can pinpoint where I went wrong. So I started with drawing my FBD's and what not, and I want to find the Tension in the string first. I set this up by using m1, since it's hanging and should be fairly straightforward. mg-T = ma (8.32)(9.8)-T = (8.32)(2.21) I got T = 63.1488N After having that I figured I would use m2's forces in the x direction to solve for μ. I set up the equation by the following: Fxnet = Tcos34-mgsin34-μmgcos34 = ma, and here I used acos34 since that would be the acceleration in the x direction. I solved and got μ = .1068 but that is the wrong answer. I am very confused. Thank you in advance for all help!
