Question
Rank the following situations in order of the magnitude of the impulse of the net force, from largest value to smallest value. if they have equal values, overlap them.A) a 200kg object initially moving west at 20m/s comes to rest in 10 s. B) a 200kg object initially moving west at 20m/s comes to rest in 30 s. C) 400kg object moving south at 10m/s speeds up for 20 s, after which it is moving south at 15m/s D) a 300-N net force directed toward the north acts on a 200kg object for 15 s. E) 400kg object moving south at 20 m/s speeds up for 20s, after which it is moving south at 25m/s F) a 300-N net force directed toward the north acts on a 600kg object for 15 s.
please help! i know impulse is change in mv but where do you go from there? thanks! Rank the following situations in order of the magnitude of the impulse of the net force, from largest value to smallest value. if they have equal values, overlap them.
