If a man pulls a square-shaped box of mass 10 kg with the force of 50 Newton and body start to accelerate in the direction of force with 2 m/s2. What will be the value of the coefficient of friction and the type of frictional force?
1
0.3, Static friction
2
0.3, Kinetic friction
3
0.2, Static friction
4
0.2, Kinetic friction
