Question:
A block of mass m is at rest at the origin at t = 0. It is pushed with constant force F0 from x = 0 to x = L across a horizontal surface whose coefficient of kinetic friction is μk = μ0(1 – x/L). That is, the coefficient of friction decreases from μ0 at x = 0 to zero at x = L.
a. Use what you’ve learned in calculus to prove that
b. Find an expression for the block’s speed as it reaches position L.
