Penjelasan:
Vo = 20 m/s
a = -10 m/s²
Vt = Vo + at
0 = 20 + (-10) x t
0 = 20 - 10t
10t = 20
t = 20/10
t = 2 s
diketahui :
v0 = 20 m/s
vt = 0
a = 10 m/s
ditanya : s
jawab :
[tex] {vt}^{2}[/tex] = [tex] {vt}^{2} [/tex] + 2 a s
0 = [tex] {20}^{2} [/tex] + 2(-10)s
0 = 400 - 20s
20s = 400
s = 400 / 20
s = 20 m
