the moon rock since its gravity is 10x lighter than earths
Answer:
2 km due south.
Explanation:
We need to find the displacement of 4km south,2 km north, 5km south, and 5 km north.
Let south is negative direction and north is positive direction.
The shortest path covered by an object is called its displacement.
D = -4+2-5+5
D = -2 km
So, the displacement is 2 km and it is in south direction.
Your hand is not capable of moving fast enough for sound to come out of it.
The "i" component of a vector is in the x-direction. Therefore, the x-component is 3 m/s.
