Homework Statement
A block of mass " lying on a ramp tilted at an
angle with the horizontal is connected to
another block of mass # by a light string passing
over a frictionless pulley as shown. If the block
slides up the ramp with a constant velocity ),
what is the coefficient of kinetic friction $%?
Homework Equations
f=ma
The Attempt at a Solution
ƩF1xx = m1a
Ft - μkFn = m1a
ƩF1y = m1a1y
Fn - mgcosθ = m1a1y
I can figure out the Ft from the other mass. But where I am stuck is I have 3 unknowns and 2 equations. I can't find a way to solve for μk when I don't have θ.
Thanks for the help
