Consult interactive solution 4.65 before beginning this problem. a toboggan slides down a hill and has a constant velocity. the angle of the hill is 6.00° with respect to the horizontal. what is the coefficient of kinetic friction between the surface of the hill and the toboggan

Explanation:

It is given that,

The angle of the hill is 6.00° with respect to the horizontal. Let is the coefficient of kinetic friction between the surface of the hill and the toboggan.

A toboggan slides down a hill and has a constant velocity. On an inclined plane, force of friction will also act.

Force of friction, ...........(1)

Normal force, ............(2)    

From equation (1) and (2) :

So, the coefficient of kinetic friction between the surface of the hill and the toboggan is 0.14. Hence, this is the required solution.                    

half of a circle

explanation:

the arrow and the top of the circle is matching together. it is not a polygon because a polygon would always be the same shape. therefore, an half of a circle is called semicircle so you would find the radius of it.

answer: option c.

explanation:
