The density of an unspecified material is 3.27 g/cm (cubed) . if the mass of a block of this material is 10.9kg, what is the volume of the block in cubic meters?
A Wooden block is pulled to the right across a level surface at a constant velocity by a force of 47 Newtons, the coefficient of kinetic friction between the block and surface is 0.62:
A-What's the magnitude of the weight of the block?
B-what's the mass of the block?
