The unit of force is the 'Newton'.
1 newton is the force that accelerates 1 kilogram of mass 
at the rate of 1 meter per second-squared.
                   1 N  =  1 kg-m/s²
-- A force of 1 pound is about  4.448 newtons.
-- A force of 1 newton is about  3.6 ounces.
        
                    
             
        
        
        
Answer:
The coefficient of kinetic friction between the sled and the snow is 0.0134
Explanation:
Given that:
M = mass of person = 52 kg
m = mass of sled = 15.2 kg
U = initial velocity of person = 3.63 m/s
u = initial velocity of sled = 0 m/s
After collision, the person and the sled would move with the same velocity V.
a) According to law of momentum conservation:
Total momentum before collision = Total momentum after collision
MU + mu = (M + m)V

Substituting values:

The velocity of the sled and person as they move away is 2.81 m/s
b) acceleration due to gravity (g) = 9.8 m/s²
d = 30 m
Using the formula:

The coefficient of kinetic friction between the sled and the snow is 0.0134
