8 pts) A block with an initial speed v moves across a rough surface where it experiences a
constant force of kinetic friction. The block travels a distance D across the surface before coming
to rest.
If the same block is instead given an initial speed of 2v, how far will it travel before coming to
rest?
A.3D
B.4D
C.2D
D. D
E. We cant tell without knowing the coefficient of kinetic friction.
