Quick comprehension check

A 2 kg block is placed on an inclined plane with an angle of 25°. The coefficient of static friction between the block and the plane is 0.3. Will the block slide down the plane? Show your calculations and explain your reasoning. A 3 kg box is on an inclined plane with an angle of 30°. The coefficient of kinetic friction between the box and the plane is 0.25. If the box is given a slight push downwards, will it accelerate down the plane? Show your calculations and explain your reasoning.
