A dog-sled driver prepared for her race. Her sled was loaded with sled equipment,
but on snow and ice, the dogs moved the
heavy sled. Each dog pulled with a force
of 600 N
During the race, she came to an area of
grass and dirt instead of snow. The sled

one of the dogs. One of them is pulling
with a force of less than 600 N.
How would you respond to the dog-sled
driver?
