Quick comprehension check

A 5 kg block rests on an inclined plane angled at 30° to the horizontal. The coefficient of static friction between the block and the plane is 0.4. Calculate the force of static friction acting on the block. A 10 kg box is being pushed up an inclined plane angled at 20° to the horizontal. A force of 30 N is applied parallel to the plane. The coefficient of kinetic friction between the box and the plane is 0.2. Calculate the force of kinetic friction acting on the box.
