During a crash test, a truck of mass 1433 kg was driving at 12 m/s when it crashed into a stationary car with mass 862 kg. The truck and car stick together after the collision. How fast is the stuck-together car and truck going after the crash?

car stops. he keeps going = he has inertia

reserve is the answer

your answer is, orbit around the nucleus

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
