a firefighter 100m away from a burning building directs a stream of water from a fire hose at an angle of 30 degrees above the horizontal. If the velocity of the stream is 60m/s, at what height will the streal of water strike the building?

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

that would be because of both gravity and friction. so     c

+15-35=-20

going in opposite directions
