In the cabin of a jetliner that cruises at 600 km/h, a pillow drops from an overhead rack into your lap below. Since the jetliner is moving so fastm why doesnt the pillow slam into the rear of the compartment when it drops? What is the horizontal speed of the pillow realitive to the ground? Realitive to you inside the jetliner?
Is that why the air stewardess' always bring the pillows from the back? :)
The pillow is moving at the same speed as you when it drops. See Newtons first law.
