Suppose a person whose mass is m is being held up against the wall with a constant tangential velocity v greater than the minimum necessary. find the magnitude of the frictional force between the person and the wall.

In the magnitud is in good

Answer:

friction force must be equal to the magnitude of weight of the object

Explanation:

When the object is stuck against the wall

then we will have

[tex]F_n = \frac{mv^2}{r}[/tex]

also we know that

[tex]mg = F_f[/tex]

so if the block is at rest and not sliding then in vertical direction the force must be balanced

so here we can say

[tex]F_g = F_f[/tex]

so friction force must be equal to the magnitude of weight of the object
