A crate of mass 10.6 kg is pulled up a rough incline with an initial speed of 1.52 m/s. The pulling force is 106 N parallel to the incline, which makes an angle of 19.4 degree with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.06 m. How much work is done by the gravitational force on the crate? J Determine the increase in internal energy of the crate-incline system owing to friction. J...

This question is worth 25 marks. A block of stone, with a mass of 2600 kg, is being carried on a light sledge. It is held at rest on a smooth ramp by workers pulling on a rope attached to the block. The ramp makes an angle of 14° with the horizontal, and the rope is parallel to the ramp. Each worker can pull with a force of maximum magnitude 350 N. a.Draw a force diagram of the situation described....

A box with a mass of 10 kg is pushed with a constant force of 100 N a distance of 3.0 m up a ramp that makes an angle of 30 from the horizontal. The coefficient of kinetic friction between the box and the ramp is 0.35. a. Compute the work done by each of the four forces acting on the box. b. Assuming the box starts at rest, determine the speed of the box at it reaches a distance...

A crate of fruit with a mass of 39.5 kg and a specific heat capacity of 3750 J/(kg⋅K) slides 7.70 m down a ramp inclined at an angle of 37.9 degrees below the horizontal. 1. If the crate was at rest at the top of the incline and has a speed of 3.00 m/s at the bottom, how much work Wf was done on the crate by friction? Use 9.81 m/s2 for the acceleration due to gravity and express your...

A mass m = 12 kg is pulled along a horizontal floor with NO
friction for a distance d =6.5 m. Then the mass is pulled up an
incline that makes an angle θ = 25° with the horizontal and has a
coefficient of kinetic friction μk = 0.44. The entire
time the massless rope used to pull the block is pulled parallel to
the incline at an angle of θ = 25° (thus on the incline it is
parallel...

friction for a distance d =6 m. Then the mass is pulled up an
incline that makes an angle θ = 37° with the horizontal and has a
coefficient of kinetic friction μk = 0.4. The entire
time the massless rope used to pull the block is pulled parallel to
the incline at an angle of θ = 37° (thus on the incline it is

1) A cart for hauling ore out of a gold mine has a mass of 447 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.63∘ incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 436 N force for a distance of 115 m by means of a rope that is parallel to the...
