Answer:
True

Explanation:
Physical fitness is defined as the health state of the body and its ability to carry on with the daily occupation as well as sports.
The everyday lifestyle affects this physical fitness, in case you are not used used to "moving" in your daily life, your body will be sort of lazy and lack the power and ability to carry on with the daily occupation as well as sports.
In case your daily lifestyle involved motion, your body will be used to doing activities which will help improve your physical fitness.

use the formula

$f = ma$

where f-force

m-mass

a-accleration

1kN=1000N

so apply

4000=1000×a

a=4m/s

You are on the roof of the physics building of your school, 46.0 m above the ground. Your physics professor, who is 1.80 m tall,

Elena L [17]

Answer:

The professor should be 3.60 meters away from the place where the egg would fall.

Explanation:

To calculate this first we need to calculate the time it would take for the egg to fall the distance from the roof to the professor's head (46m-1.8m=44.2m).

The formula for free fall is:

y=1/2*g* $t^{2}$

solving for t it would be

$\sqrt{\frac{y}{g*1/2}} =t$

replacing

$\sqrt{\frac{44.2m}{9.8m/s^2*1/2}} = t = 3.00s$

Now that we have the time it would take the egg to get from the roof to the desired height we need to calculate the distance the professor would travel in that time so we know to release the egg when he's exactly at that distance.

Since he is traveling at a constant speed the formula is

x=v*t

replacing

1.20m/s * 3.00 s = x = 3.60 m
