A 50.0 kg object rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.300 and the coefficient of kinetic friction is 0.200. What is the friction force on the object if a horizontal 140 N push is applied to it?

Explanation:

Given:

Now the value of limiting frictional force offered by the contact surface tending to have a relative motion under the effect of force:

where:

normal force of reaction acting on the body= weight of the body

As we know that the frictional force acting on the body is always in the opposite direction:

So, the frictional force will not be at its maximum and will be equal in magnitude to the applied external force and hence the body will not move.

so, the frictional force will be:

im guessing the west of station b

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
