A sled of mass 50.0 kg is pulled along flat, snow-coveredground. The static firiction coefficient is 0.30, and the kineticfriction coefficient is 0.10.
a. What does the sled weigh?
b. What force will be needed to start the sled moving?
c. What force is need to keep the sled moving at a constantvelocity?
d. Once moving, what total force must be applied to thesled to accelerate it at 3.0 m/s squared?
