A sled of mass 50.0 kg is pulled along flat, snow-covered ground. The static friction coeffi- cient is 0.30, and the kinetic friction 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 needed to keep the sled mov- ing at a constant velocity? d. Once moving, what total force must be applied to the sled to accelerate it at 3.0 m/s²? A sled of mass 50.0 kg is pulled along flat, snow-covered ground.
