A35g bullet strikes a 5kg (.005g) stationary piece of lumber and embeds itself in the wood. the piece of lumber and bullet fly off together at 8.6m/s. what was the original speed of the bullet? /s
Answer from: Quest
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
