Answer 2

Answer:

20s

please rate, hope it helps

Explanation:

vy_initial = 100m/s

then

vy_final = vy_inital + g.t

if we assume g = -10 m/s^2 and vy_final is 0m/s (on the top of motion)

then

0 = 100-10.t

t=10second this is the time needed from launch poiint to the top of trajectory

then we will multiply it by 2

t_total = 10 . 2= 20s
