Johnny looked in the garage and found a long board some bricks a wheelbarrow a rake and crowbar can he use any of these things to free his workbook how could he do it?

Johnny can use the long board and the bricks to create a lever system. By placing one end of the board on the bricks as a fulcrum, he can use the crowbar to apply force on the other end of the board, effectively lifting or moving an object that is trapping his workbook. If the workbook is pinned down or stuck, he might also use the wheelbarrow to transport any heavy items blocking access to it.
