A 15kg box is a rest what is its weight? weight =mass*gravity 15kg*9.81 see what unity you need!!!

anonymous · Answer

what is the normal force. If the table is horizontal the normal force is just the weight. if this table is angled use geometry (triangles) to find the force that is perpendicular to the table.

anonymous · Answer

The normal force will push back the same as it is being pushed agents. total mass* gravity 29 kg*9.81m/ss Keep units in mind you probably have convert everything to grams 1kg=1000g

anonymous · Answer

last one 
14kg*9.81m/ss It is like the 15kg box is now the table.
