Question:medium
A constant horizontal force of 100 N is exerted on a 50 kg box initially at rest. When the box has moved a distance of 2 m, its speed is 2 m/s. The coefficient of kinetic friction between box and floor is (g = 10 m/s²)

- There are two inclined surfaces of equal length inclined at an angle of \(45^\circ\) with the horizontal. One of them is rough and the other is perfectly smooth. A given body takes 2 times as much time to slide down on the rough surface than on the smooth surface. The coefficient of kinetic friction (\(\mu_k\)) between the object and the rough surface is close to :
