On a certain planet an object of mass m is moving with an initial speed of 4 m/s. It comes to rest after traveling a horizontal distance of 10 m.
 
  If the coefficient of kinetic friction between the object and the surface is 0.2, what is the value of g on that planet?
  A) 4 m/s2
  B) 6 m/s2
  C) 8 m/s2
  D) 10 m/s2
  E) 12 m/s2

  A) 9.8 m/s
  B) 6.3 m/s
  C) 3.6 m/s
