A car travels along a straight road to the east for 100 meters in 4 seconds, then has to turn around

and goes back west for 50 meters in 1 second.

Determine average speed and average velocity.

90 m/s, 70 m/s

Explanation:

Given

A car travels 100 m  east for 4 seconds and then turn around

goes back west for 50m  in 1 sec

Distance traveled in the east is

Distance traveled in the west is

Total distance

total displacement

total time

Average speed

Average velocity

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
