The 6-lb particle is subjected to the action of its weight and forces f1 ={2i + 6j - 2tk} lb, f2 = {t2i - 4tj - 1k} lb, and f3 = {-2ti} lb, where t is in seconds. determine the distance(ft) the ball is from the origin 2 s after being released from rest.

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
