Answer:
Magnitude of the force is 2601.9 N
Explanation:
m = 450 kg
coefficient of static friction μs = 0.73
coefficient of kinetic friction is μk = 0.59
The force required to start crate moving is .
but once crate starts moving the force of friction is reduced .
Hence to keep crate moving at constant velocity we have to reduce the force pushing crate ie .
Then the above pushing force will equal the frictional force due to kinetic friction and constant velocity is possible as forces are balanced.
Magnitude of the force
Mass movement is the movement of surface materials caused by gravity. A great example would be a mud slide.
To solve this problem it is necessary to apply the concepts related to the magnetic field.
According to the information, the magnetic field INSIDE the plates is,
Where,
Permeability constant
Electromotive force
r = Radius
From this deduction we can verify that the distance is proportional to the field
Then the distance relationship would be given by
On the outside, however, it is defined by
Here the magnetic field is inversely proportional to the distance, that is
Then,
Use your feet to stop it since it is soccer you can't use your hands!!!! P.S. you can't use gravity.
