You need to push a cupboard by applying a horizontal force F on its side. The cupboard width is L, height is H and mass is m. You are applying the force at a point that is a height h above the floor. The coefficient of kinetic friction between the dresser and the floor is u. The ground exerts upward normal forces of magnitudes Np and No at the two ends of the dresser. a) How much force do you need to apply for the cupboard to move with constant velocity? b) What are the magnitudes of normal forces Np and Na if the cupboard legs are separated by a distance L? c) What is the maximum height h where you can push the cupboard before it tips over? F H Pl Np N.

1) A small steel block and a magnet rest on a horizontal frictionless table. The steel block weighs 0.07N and the magnet is fixed to the table. The force acting on the steel block by the magnet is inversely proportional to the square of the distance between the steel block and the magnet. When the block is 26cm away from the magnet, the force becomes 0.145N. If the block starts its motion from rest at this position, what is the magnitude of the velocity of the block when it is 9.5cm away from the magnet?
