Jani is planning to go to Jojo's house, Jani has to walk 30m going east. Then, he will head to the north at a distance of 40 meters. Afterwards, he will walk 70m going west.
1. Determine the total distance travelled by Jani's.
2. Calculate Jani's displacement.
3. What is the difference between the path taken by Jani and the straight line connecting the starting and the last points of the path.
distance: add all the lengths
displacemetn=sqrt(W^2+N^2)=sqrt((-30+70)^2 +40^2)=40sqrt2 this is magnitude. check the math.
