Answer 1

Answer #1

apply the formula for Max height H = u^2/2g

where u is intial speed = 20 m/s

g is accletation due to gravity

so

H = (20*20)/(2*9.8)

H = 20.40 m -----------------<<<<<<<<<<<<<<<<Answer

-----------------------------------------------

apply time period of flgiht

t = 2u/g

t = (2*20)/9.8

t = 4.08 secs-----------------<<<<<<<<<<<<<Answer
