For how long a time must a tow truck pull with a force of 550 N on a stalled 1200 kg car to give it a forward velocity of 2.0 m/s?
Law of conservation of momentum is related to which law of Newton's motion?
Newton's third law
If a 2,500 kg truck is moving at 2 m/s and a 2,000 kg car is moving at 3 m/s, which one has greater momentum?
you answer the question and take a full point or let another team answer it and take half the points.
The car
For a constant force, if the duration of impact upon an object is doubled, how is the impulse affected?
will doubled

what are the conditions under which the total momentum of a system of particles is conserved?
Isolated and closed system
Two cars, one twice as heavy as the other, move down a hill at the same speed. Compared to that of the lighter car, the momentum of the heavier car is ___________ as much.
Twice

your team have lost 200 point
20.8 m/s
