A 3.0kg crate slides across a warehouse floor at 8.0m⋅s−1. For the first 5.0m, the coefficient of kinetic friction is μk1=0.05. Beyond that, the floor is rougher with μk2=0.20. Assuming the coefficients are constant in their respective regions, which is closest to the total distance the crate travels before coming to rest?
a) 16m
b) 26m
c) 20m
d) 35m
