Acrazy dog runs 300 meters east, changes his mind and then runs 200 meters west. he then changes his mind again and runs 500 meters east. this entire trip takes 2 minutes. a) what is the total distance traveled? b) what is the total displacement? c) what was the dog’s average speed? d) what was the dog’s average velocity?

Distance 1000 meters

Displacement: 600 meters east.

Average speed: 500 meters per minute

Average velocity: 300 meters per minute

Explanation:

In order to calculate this you just have to know the difference between distance and displacement, distance is the total meters that someone walk or run or moved accros, and displacement is a vector, that is the result of how far away from the starting point the object finished. Then with this two values you can calculate average speed which is distance between time, and average velocity which is displacement between time.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
