Diketahui :
Vo = 70 m/s
g = 9,8 m/s²
Ditanyakn : h max ?
dijawab :
hmax = Vo²/2g
= 70²/2x9,8
= 4.900/19,6
= 250 m
bagian e :
h = 100 m
g = 9,8 m/s²
ditanyakn h saat t=2 s ?
dijawab :
Jarak yg ditempuh saat t = 2 s
St = 1/2 x g x t²
= 1/2 x 9,8 x 2²
= 1/2 x 39,2
= 19,6 m
Jadi jarak dr tanah = h awal - s yg ditempuh
= 100 - 19,6
= 80,4 m
