A dad pulls his child on a sled at a constant speed across a rugged snowy road with a force of 159 N in a direction of 42° above the horizontal. The mass of the child and sled is 38 kg. Compute the coefficient of friction. (HINT: Set up the force equations and Derive the expression the coefficient of friction between sled and snow.)
A sled weighing 60.0 N is pulled up a snowy hill inclined at 10 degrees to the horizontal at a constant speed so that the coefficient of kinetic friction between sled and snow is 0.070. A penguin weighing 70.0 N rides on the sled. If the coefficient of static friction between penguin and sled is 0.950, find a). the force of friction between the sled and the snow, b). the force of static friction between the penguin and the sled,...
A mother pulls her child on a sled at a constant speed across a rugged snowy road with a force of 160 N in a direction of 45° above the horizontal. The mass of the child and sled is 41 kg. What is the coefficient of friction. Write out all steps and explain.
v = 2 m/s F = 100 N 3. (4 points) A child pushes a 20 kg box across a wood floor as shown in Figure 3. The force exerted by the child is 100 N and horizontal.
