Two arrows are fired horizontally with the same speed of
30.0m/s. each arrow has a mass of 0.100 kg. one is fireddue east
and the other due south. find the magnitude anddirection of the
total momentum of this two-arrow system. specify the direction with
respect to due east.

Explanation:

Given

mass of each arrow=0.1 kg

velocity of arrow=30 m/s

One arrow is fired u=due to east and another towards south

Momentum of first arrow

Total momentum P

magnitude

direction

clockwise w.r.t to east

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
