The force of friction acting on him is 122 N. The correct answer is option C
<h3>
What is Friction ?</h3>
Friction is a force that opposes the motion of a static or a moving object.
Given that Barry slides across an icy pond. The coefficient of kinetic friction between his shoes and the ice is 0.15. If his mass is 83 kg
The given parameters are;
- Coefficient of kinetic friction μ = 0.15
- Frictional force
= ?
The normal reaction N on the body = mg
N = 83 x 9.8
N = 813.4 N
The Frictional force formula is = μN
= 0.15 x 813.4
= 122.01 N
Therefore, the force of friction acting on him is 122 N approximately.

<u>Distance = 12 m</u>
<u>Explanation:</u>
Distance covered by the runner is same as the total path that he has ran. Here, a person starts at 0 position and goes in one direction to position 12 m. Since the initial point is 0 and the final position is 12, the total distance is calculated by adding the 2 points as: 0+12 = 12 m. So the distance covered and the displacement both are same which is 12 meters.
Distance traveled is the full length of the path covered between two points. It is not a vector and the direction is nil and no negative sign. Example : The distance walked by the teacher is 3.0 m ,The distance walked by a passenger is 5.0 m. Also, the distance traveled need not be equal to the magnitude of the displacement which is the distance between the two positions.
To slow down or reduce speed.
