Answer:
Kinetic frictional force will be equal to 56.84 N
Explanation:
We have given mass of the skier m = 58 kg
Acceleration due to gravity 
Coefficient of kinetic friction 
We have to find the kinetic frictional force
Kinetic frictional force is given by

So kinetic frictional force will be equal to 56.84 N
Answer:
C. The entropy of the system (ice plus water) increases because the process is irreversible.
<u>Complete Question:</u>
A hockey player swings her hockey stick and strikes a puck. According to Newton’s third law of motion, which of the following is a reaction to the stick pushing on the puck?
A. the puck pushing on the stick
.
B. the stick pushing on the player
.
C. the player pushing on the stick
.
D. the puck pushing on the player.
<u>Correct Option:</u>
According to Newton’s third law of motion the puck pushing on the stick is a reaction to the stick pushing on the puck.
<u>Option: A</u>
<u>Explanation:</u>
As when the hockey exert force on the puck (which is a flat ball basically used in ice hockey) then this action by hockey will receive equal and opposite reaction by puck. Thus when the stick is pushing on the this flat ball, then puck also push the stick. This is understood by newton's third law pf motion, where action and reaction forces are subject of discussion, displaying their is pair of forces applied among the interacting objects. This form is observed more practically in life and very frequent.
