A heavy sled is being pulled by two people, as shown in the figure. The coefficient of static friction between the sled and the ground is μs=0.587 , and the kinetic friction coefficient is μk=0.403 . The combined mass of the sled and its load is m=351 kg . The ropes are separated by an angle ϕ=26.0° , and they make an angle θ=30.4° with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension required to get the sled moving?If this rope tension is maintained after the sled starts moving, what is the sled's acceleration?

A car is being pulled out of the mud by two forces that are applied by the two ropes shown in the drawing.
A car is being pulled out of the mud by two forces that are applied by the two ropes shown in the drawing. The dashed line in the drawing bisects the 30.0° angle. Themagnitude of the force applied by each rope is 2900 newtons (N). (a) How much force would a single rope need to apply to accomplish the same effect as the two forcesadded together? (b) What angle would the single rope make relative to the dashed line?

Show step by step solution please. A sled weighing 100 N is pulled horizontally across a frozen lake such that the coefficient of kinetic friction between the sled and the snow is 0.1. Penny is riding the sled and she weighs 195 N. If the coefficient of static friction between Penny and sled is 0.7, find the maximum horizontal force which can be applied to the sled before she begins to slide off.

A mass m = 17 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.06, for a distance d = 5.1 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 28° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 28° (thus on the incline it is...
