Yes. You'll find that writing the frictional force in terms of m,g, and u and setting it equal to ma will result in the masses canceling out.

If you solve the equation for FF=ma, you'll find that the m's cancel out.

So, would the path difference just be 10λsinΦ + (10λ+a)sinθ? Is the trig right?

Homework Statement Consider a plane wave (of wavelength λ) incident on a wall at an angle Φ = 30. There are two slits in the wall separated by a distance d=10λ. Each slit has width a<<λ. Rays emerging from the slits propagate to a distant screen where an interference/diffraction pattern may be...
