Atoy rocket, launched from the ground, rises vertically with an acceleration of 18 m/s^2 for 18 s until its motor stops. disregarding any air resistance, what max- imum height above the ground will the rocket achieve? the acceleration of gravity is 9.8 m/s^2. answer in units of km.

8271.92 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

Equation of motion

The height reached at 18 seconds is 2916 m

The velocity at 2916 m is 324 m/s

Maximum height reached by the toy rocket is 2916+5355.92 = 8271.92 m

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."

overcharge is the right answer system
