Use the following information to answer the next two questions. A sled with waxed hickory runners rests on a horizontal, dry snowy surface. A person wishes to pull the sled, which has a mass of 15 kg, across the horizontal surface. The coefficient of static friction is given by /, = 0.20, and the coefficient of kinetic friction is given by /, = 0.14. backward - - forward 4. The magnitude of the minimum horizontal force required to get the sled moving is N. (Input the numerical value only, as the units have already been indicated.) * Your answer 5. Assuming that the sled is in motion with an applied horizontal force of 150 N, the magnitude of its acceleration is _ m/s2. (Input the numerical value only, as the units have already been indicated.)
