Answer:

Explanation:
first ball rolls on the porch by total distance

Then again it will move on horizontal floor

also in vertical direction it will drop down

so we have



so magnitude of net displacement of the ball is given as


Explanation:
Distance covered = Total distance travelled by the car
Since the car travels to school and back to home again,
Total diatance covered = 8 + 8 = 16km
Displacement = Shortest distance between start point and destination.

the start and destination point are same.
So Displacement = 0
