Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

439 kg, including its load. The cart runs along a straight
Track
Rope
stretch of track that climbs a shallow 4.59° 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
426 N force for a distance of 185 m by means of a rope that
is parallel to the slope but makes an angle of 14.3° with
A
„Track incline
the track.
.Horizontal ground
Model the rolling resistance of the cart as though it were
sliding on the track with a coefficient of friction of 0.0159.
Use g = 9.81 m/s², and note that angle A in the image is the
angle of the incline while angle B is the angle the rope
makes with the track.
Find the work Wa that the donkey performs on the cart
during this process.
