Una persona se encuentra descansando se pone de pie y corre 0.8 km a una velocidad de 7m/s, determina su aceleracion

Explanation:

I assume that by "velocity" you refer to the average velocity of the man during the trip.

In that case, we have the following data:

(average velocity)

s = 0.8 km = 800 m (distance covered by the man)

Therefore, we can find the total time of the trip by using

Now, we know that the motion during this trip is a uniformly accelerated motion, so we can find the acceleration by using the suvat equation:

where

u = 0 is the initial velocity (the man starts from rest)

a is the acceleration

Using s = 800 m and t = 114.2 s, we find:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
