with
20 m/s
Motion
plane
A ball is thrown vertically
downward
a velocity
from the top
of
a tower
It
hits the
ground after some time with
a velocity
OF 80m/s, the
height of the tower is :
(g = 10 m/s)​

Answer 1

Answer:

340m is the answe

Explanation:

as we know, v^2=u^2+2gh

or, 2gh=u^2+v^2

or,h=u^2+v^2/2g

or,h=(20)^2+(80)^2/2×10

or,h=400+6400/20

or,h=6800/20

or,h=340

h=340m
