 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,$\mu_s$ ?
