Ablock of aluminum has a mass of 39.589 g and measures 5.10 cm by 2.50 cm by 1.15 cm. what is the density of the rectangular aluminum block?

In order to calculate the density of the block, we must calculate its volume first.

The volume of the block is given by:

So now we can calculate the density of the block as the ratio between its mass and its volume:

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

find the sum of the two horizontal vectors and the sum of the two vertical vectors
