Question:

A box is lying still on an inclined plane. The inclination angle (from the horizontal) of the plane is alpha=30^circ .  At a certain moment, the box is being punched. This punch sets the box in motion up the inclined plane. The box climbs until it comes to a stop. The scenario is depicted in the clip. The coefficient of kinetic friction between the box and the plane is  mu_k=0.5

 

What is the lower limit that can be placed on the value of the static friction coefficient, large mu_s?
