If a 10 kg mass, moving at 5 m/s to the right, hits and sticks to a 16 kg mass, moving at 19 m/s to the right, and they travel off together at the same speed to the right, find that speed. B. If a 5 kg mass, moving at 7 m/s to the right, hits and sticks to a 19 kg mass, moving at 6 m/s to the left, and they travel off together at the same speed, find that speed.(Note: this question is from an old question paper how else would i get mark scheme. So pls look properly before rejecting) Since impulse( change in momentum) is mv - mu mv=0 mu=1400 shouldnt impulse be 0-1400 ? So answer should be negative right? Why does markscheme show positive answerWhat is the momentum of a fuel tanker that has a loaded tonnage of 800,000 tons (lets use metric tons ... 1 ton = 1000kg) and a speed of 36.0 mph in kg*m/s?
