Question

solve this..........................!​

Answer 1

ANSWER= 20m

EXPLANATION ➡️

given

initial velocity (u) = 20m/s

finale velocity (v) = 0 ( as on maximum height velocity is zero)

we require time to calculate maximum time and to calculate time use this equation

v= u+at

from this equation you get value of time

to get maximum height put value of time in following equation

S= ut-gt²/2

Answer 2

Answer:

solution:-

v = u + at

0=20+10xt

t = 20/10 = 2sec

s=ut-1/2gt sq.

s=20x2 - 1/2 10 sq.

s= 40-40/2

s= 20m
