Answer:
F = 250 N
Step-by-step explanation:
Given that,
Mass of an object, m = 50 kg
The coefficient of kinetic friction = 0.5'
We need to find the force of kinetic friction. The kinetic friction is given by the formula as follows :
[tex]F=\mu N[/tex]
N is normal force, N = mg
[tex]F=0.5\times 50\times 10\\\\F=250\ N[/tex]
Hence, the force of kinetic friction is 250 N. Hence, the correct option is (d).
