HW Lecture 8: Consider a block that is free to slide down a rough plane(i.e. there is a frictional force f ) that is inclined at an angle 0 to the horizontal, as shown in below Figure. If the height of the plane is h and the block is released from rest at the top, what will be its speed when it reaches the bottom? Hint: The net force in the x-direction is equal to f HN where N represents the normal force and is the coefficient of sliding friction.
