Vo = 80m/s
g = 10m/s^2
Ditanya
lama waktu diudara Ttotal.??
Vt = 0 -> kecepatan akhir
Vt=Vo - g.t
0 = 80 - 10.t
80 = 10t
t = 8s
T total = 2t = 2 .8
Ttotal = 16sekon -> waktu yng diperlukan untuk naik dan turun kembali
Tinggi maks..?
Vt² =Vo² - 2gh
0 = 80² - 2.10.h
6400 = 20h
h = 6400 / 20
h = 320 m
