Answer:
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.

See attached photos for the solution:
k is the rate constant
T is the absolute temperature (in kelvins)
A is the pre-exponential factor, a constant for each chemical reaction. According to collision theory, A is the frequency of collisions in the correct orientation
Ea is the activation energy for the reaction (in the same units as R*T)
R is the universal gas constant.
