Did you know?
Did you know that the motion of an object can be determined by the forces acting upon it? In the given scenario, a student is applying a force of 100 n at an angle of 55 degrees above the horizontal to a 20 kg box. The motion of the box can be described based on the coefficients of friction involved. The coefficient of static friction, which is 0.43 in this case, determines if the box will remain at rest or start moving. If the applied force is not enough to overcome the static friction, the box will not move. However, if the applied force exceeds the static frictional force, the box will overcome its resistance and start moving. Once in motion, the coefficient of kinetic friction, which is 0.3, comes into play. This force opposes the motion of the box. Therefore, in this scenario, the box will remain stationary if the applied force is less than or equal to 100 n (the maximum static frictional force), but will start moving if the applied force exceeds this value.
