Alizard ran 3 meters from his rock to his friend's house. he ran
back halfway and stopped. what is his distance traveled?
distance traveled = _ m

The total distance traveled by a lizard that ran 3 meters from his rock to his friend's house and then ran back halfway and stopped is 4.5 meters.

The lizard ran 3 meters from his rock to his friend's house, so:

Then, he ran back halfway and stopped:

The total distance traveled is:

We need to remember that the distance is a scalar that not depends on the direction of motion.  

Therefore, the total distance traveled by the lizard is 4.5 meters.

Distance traveled, d = 4.5 meters

Explanation:

It is given that, a lizard ran 3 meters from his rock to his friend's house, distance covered by lizard, d₁ = 3 m

He ran  back halfway and stopped, now the distance covered,

We need to find the distance traveled. The overall path covered by an object during its entire journey is called distance covered.

To find the distance covered by the lizard we need to simply add both distances as :

d = 4.5 meters

So, his distance traveled is 4.5 meters. Hence, this is the required solution.                                          

magnitude and direction

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
