Physics student is dropped. if they reach the floor at a speed of 3.2 m/s, from what height did they fall?

0.52 m

Explanation:

The motion of the studnet is an accelerated motion, with constant acceleration (acceleration of gravity) toward the ground. We can find the distance covered by the student (which is equal to the height from which he falls) by using the SUVAT equation:

where

v = 3.2 m/s is the final speed

u = 0 is the initial speed

a = 9.8 m/s^2 is the acceleration

d is the distance covered

By re-arranging the equation, we find:

what best describes physical development during adolescence is the development of secondary sex characteristics happens at a rate unique to each individual.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
