- A 5.00-kg box is initially at rest on a level surface. The coefficient of static friction between the box and the surface is 0.400. Calculate the maximum force you can apply before the box starts to move, if the force is directed at an angle of 30 degrees from the horizontal, with the vertical component downward.

Which of the following statements must be true about the magnitude of the frictional force that acts on the crate? O It is least equal to the weight of the crate. O It is equal to n. O It is larger than the weight of the crate. O It is greater than the component of the gravitational force acting down the ramp. O It is equal to the component of the gravitational force acting down the ramp.1O C A cart for hauling ore out of a gold mine has a mass of 439 kg , including its load. The cart runs along a straight stretch of B Track track that climbs a shallow 4.75° incline. A donkey, which is Rope trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 441 N force for a distance of 185 m by means of a rope that is parallel to the slope but makes an angle of 14.5° with the track. A „Track incline Model the rolling resistance of the cart as though it were Horizontal ground sliding on the track with a coefficient of friction of 0.0163. Use g = 9.81 m/s, and note that angle A in the image is the angle of the incline while angle B is the angle the rope makes %3D with the track. Find the work Wa that the donkey performs on the cart during this process. %3D Find the work W, that the force of gravity performs on the cart during this process. = "M Calculate the work W done on the cart by friction during this process. 87
