Question: Block A is traveling with a speed v0 on a smooth surface when the surface suddenly becomes rough with a coefficient of friction of m

Block A is traveling with a speed v0 on a smooth surface when the surface suddenly becomes rough with a coefficient of friction of m causing the block to stop after a distance d. If block A were traveling twice as fast, that is, at a speed 2v0, how far will it travel on the rough surface before stopping?

(a) d/2

(b) d

(d) 2d

(e) 4d
