6. Friction between two surfaces in contact may be lessened by changing sliding frictior friction and by reducing Kiretic the surfaces in to contact. 7. If a force of 25 lb. is needed to pull a 500 lb. weight across a tabletop, what is the coefficient of friction between the surface of the weight and that of the tabletop? 8. If the coefficient of friction between a tabletop and a certain metal is 0.150, what fc is needed to pull a 275g weight made of this metal across the tabletop at a uniform rate
