A horse is harnessed to a sled having a mass of 226 kg, including supplies. The horse must exert a force exceeding 1190 N at an angle of 34.3° (above the horizontal) in order to get the sled moving. Treat the sled as a point particle. HINT (a) Calculate the normal force (in N) on the sled when the magnitude of the applied force is 1190 N. (Enter the magnitude.) (b) Find the coefficient of static friction between the sled...

By pulling a on rope attached to a crate of mass 77.0 kg, the crate is dragged across a floor. Let the coefficient of static friction between the crate and the floor be 0.830 and the angle between the rope and horizontal is 39.1 °. Find the minimum force required to move the crate. At a later time the crate is now dragged with this same force, and has already started moving, on a wet floor where the kinetic friction...

The truck's winch exerts a horizontal force on t t he 133-kg crate in an effort to pull i down the ramp. The coefficient of static and kinetic friction between the crate and the ramp are μ-037 μ-013 respectively. If the winch exerts a 172-N horizontal force on the crate, what is the magnitude of the friction force exerted on the crate by the ramp? 18°

A 313-kg crate rests on a surface that is inclined above the horizontal at an angle of 17.0°. A horizontal force (magnitude = 414 N and parallel to the ground, not the incline) is required to start the crate moving down the incline. What is the coefficient of static friction between the crate and the incline?

A 28.0-kg block is initially at rest on a horizontal surface. A horizontal force of 73.0 N is required to set the block in motion, after which a horizontal force of 55.0 N is required to keep the block moving with constant speed. (a) Find the coefficient of static friction between the block and the surface. (b) Find the coefficient of kinetic friction between the block and the surface.
