A crate sliding down a ramp reaches the bottom of the ramp and slides across a flat floor. At the instant shown, the crate has a speed of v = 4.25 m/s . The crate comes to a stop after a distance x = 15.5 m . (Figure 1) What is μk, the coefficient of kinetic friction between the crate and the floor?

Express your answer numerically to three significant figures.

μk =

5.94×10−2
