You need to use the equations for motion with constant acceleration. Time is the variable you do not know, so use an equation that does not include time: v2=v02+2a(x-x0) The final velocity (the v on the left side of the equation) will be zero (because you will be stopped). You want to...

Thanks for the revision!

Please see the attached revised diagram showing the angle. There should be a negative sign in front of (m2)(a). On paper I wrote this down - just didn't type it correctly here. The combined equations from my work up should read: (m1)(a)+(m1)(g)(fk) = -(m2)(a)+(m2)(g)(cos30). When you say...

Homework Statement Block 1 of mass m1=2.0kg and block 2 of mass m2=3.0kg are connected by a string of negligible mass and are initially held in place. Block 2 is on a frictionless surface tilted at theta = 30 degrees. The coefficient of kinetic friction between block 1 and the horizontal...
