A 50kg box is pushed across the floor with a force of 78N.A retarding force due to friction between the box and the floor also acts on it. If it is starting from rest and attains a kinetic energy of 230J after being pushed 5m. Find out the net force acting on it. What will be the value of the retarding frictional force described above that opposes the motion?
