Answer:
μ= 0.3
Explanation:
Given that
F= 33 N
m = 11 kg
Given that crate is moving with constant velocity is means that acceleration of the crate is zero.If acceleration of the system is zero then the total force on the system will be balance.
Therefore
F= Friction force
F= μ m g
μ=Coefficient of friction
33 = μ x 10 x 11 ( take g= 10 m/s²)
3 = 10 μ
μ= 0.3
Therefore coefficient of friction will be 0.3 .
