A 3.0 kg arrow is fired 9 m/s into a stationary 8 kg block of ice as shown below. The arrow sticks into the block of ice. (Nonelastic collision) What is the velocity of the arrow & ice together when the collision has occurred?

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

it takes about 30 days for it to break down

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
