Question

help

Answer 1

Two arrows are fired horizontally with the same speed of30.0m/s. Each arrow has a mass of .100 kg. One is fired dueeast and the other due south. Find the magnitude anddirection fo the total momentum of this 2 arrow system. Specify thedirection with respect to due east.

Answer 2

@ivanmlerner

Answer 3

p=mv

Answer 4

3kgm/s

Answer 5

That is for each arrow, the total is 2 times this number.

Answer 6

What do you mean by find the direction with respect to due east?

Answer 7

angle

Answer 8

but the answer was 4.24kg m/s and 45 degree

Answer 9

i dont know hoe they got that

Answer 10

oh, ok.
What is your intuition about that? Remember that they have the same speed in perpendicular directions.

Answer 11

actually i dont know much about this becasue my teacher will teach this tommorrow

Answer 12

u mean this one

Answer 13

thats correct and the magnitude i said was correct is wrong sorry. Looking at that you can find the magnitude using the pythagorean theorem, and the direction is the vector sum of those two, so since they have the same magnitude the angle is 45°

Answer 14

ok thx
