Applying a force of 5 newtons on a wooden plank with mass m1 kg, it accelerates with an acceleration of 10 ms-2. Another plank of mass m2 kg accelerates with an acceleration of 20 ms-2 when the same force is applied. If both the planks are tied with each other and the same force is applied on them, what will be the acceleration?

A wooden block is kept on a polished wooden plank and the inclination of the plank is gradually increased. It is found that the block starts slipping when the plank makes an angle of 18° with the horizontal. However, once started the block can continue with uniform speed if the inclination is reduced to 15°. Find the coefficient of static friction between the block and the plank.
