vx =15 m s-1, t=2 sec Horizontal displacement, dx=vx. t=15× 2 =30 m

Q. A ball is thrown horizontally from a height of $100 m$ with an initial speed of $15 m s^{- 1}$ . How far does it travel horizontally in the first $2$ seconds ?

$3 m$

$7.5 m$

$30 m$

$0.3 m$

$v_{x} = 15 m s^{- 1}, t = 2 sec$
Horizontal displacement, $d x = v_{x}$ .
$t = 15 \times 2$
$= 30 m$
