Three blocks of mass 10kg, 20kg, 15kg respectively are being pushed in a row on along a horizontal surface with constant velocity by a force applied to the 10kg block.The coefficient of kinetic friction between each of the blocks and the surface is 0.18.
What is the magnitude of the force applied on the first block(10kg block)?
What is the magnitude of the force that the middle (20kg) block exerts on the 15kg block.
