a boy throws balls vertically upwards he throws whenever previous ball

1.	a boy throws balls vertically upwards he throws whenever previous ball reaches the highest point if he throws each ball after 2 seconds then how high do the ball rise
Answer» 20 m Explanation: T=4 SEC {as it TAKES HALF path for 2 SECS.} $4 = 2u \div g \\ u = 20m \\ \\ h = {u}^{2} \div (2g) \\ \\ 20m$

Answer»

20 m

Explanation:

T=4 SEC {as it TAKES HALF path for 2 SECS.}

$4 = 2u \div g \\ u = 20m \\ \\ h = {u}^{2} \div (2g) \\ \\ 20m$
