An Object Receives an Initial Push, Giving It an Initial

Multiple Choice

An object receives an initial push, giving it an initial velocity of 2.0 m/s. It then slides across a rough surface and comes to a stop after traveling a distance of 0.5 m. Assuming that the acceleration of gravity is 10 m/s², the coefficient of kinetic friction between the object and the surface is

A) 0.2.
B) 0.4.
C) 0.6.
D) unknown; the answer cannot be determined without knowing the mass of the object.
