Question

Q) An object was thrown upwards reaches the height of 39.2m .. find the velocity at which it was thrown... guyz pls answer this fast with steps I will mark u as the brainliest answer .. plz fast

Answer 1

h=39.2m
g=-9.8m/s^2
v=0
from 3rd equation of motion, we have
v^2=u^2+2gh
0=u^2+2*-9.8*39.2
-u^2=-768.32
u=
$\sqrt{768.32}$
