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;
- Mass m = 83 kg
- 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.
