#1) the person holding a baby
- holding implies no motion--> no distance--> no work


#2) the car stuck in the snow
- they're trying to get it out which means that there may be some oscillation. so technically a very small amount of work is being done.

An ice block measuring 5cm by 5cm by 5cm has a desity of 5g/cm3. What is the mass of the ice block?
Svetradugi [14.3K]


Density = (mass) / (volume)

Volume of your block = (5cm x 5cm x 5cm) = 125 cm³

5 gm/cm³ = (mass) / (125 cm³)

Multiply each side by (125 cm³):  Mass = 625 gm

Note: 
I don't know what kind of frozen substance you're working with,
but maybe you ought to be careful handling it ... I know that's
not water ice you have there.  The density of water ice is not
5 gm/cm³.  In fact, it's a little less than 1 gm/cm³.  That's why
the ice floats in your soda.
