A hand pushes a 2 kg block along a table from point A to point c as shown in the Figure below. The table has been prepared so that the left half of the table (from A to B) is frictionless. The right half (from B to C) has a non-zero coefficient of friction equal to 11. The hand pushes the block the full distance from A to C using a constant force of 6 N. The block starts off at a rest at point A and comes to a stop when it reaches point C. The distance from A to B is 0.5 m and the distance from B to C is also 0.5 m.
We will consider the block by itself as our system so all forces are external.
