An ice skater applies a horizontal force to a
20.-kilogram block on frictionless, level ice,
causing the block to accelerate uniformly at
1.4 meters per second2 to the right. after the
skater stops pushing the block, it slides onto a
region of ice that is covered with a thin layer
of sand. the coefficient of kinetic friction
between the block and the sand-covered ice is
0.28.
on the diagram in your answer booklet, starting
at point a, draw a vector to represent the force
applied to the block by the skater. begin the
vector at point a and use a scale of
1.0 centimeter = 5.0 newtons.
