Question
A ball is projected horizontally with a velocity of
$5ms_{−1}$
from the top of a tower of height 10 m. When it reaches the ground (
$g=10ms_{−2}$
)
A
Vertical component of its velocity is
$15ms_{−1}$
B
The horizontal component of its velocity is
$14ms_{_{1}}$

Verified by Toppr
Correct option is A)
$V=2gh =2×10×10 $
$Vy=102 $
$Vx=5m/s$
same
$V=Vx_{2}+Vy_{2} $
$=200+25 $
$=225 $
$=15$
