Vo = 0 m/s
Vt = 4 m/s
s = 32 m
Ditanyakn : t ?
dijawab :
Vt² = Vo² + 1/2 x a x S
4² = 0² + 1/2 x a x 32
16 = 0 + 16a
a = 16/16
a = 1m/s²
jadi wktu :
a = (Vt-Vo)/t
1 = (4-0)/t
t = 4 s
vo = 0
a = 4 m/s²
s = 32 m
ditanyakan :
t = ?
jawab :
vt² = vo² + 2as
vt² = 0 + 2 (4) (32)
vt = √ 4x64
vt = 16 m/s
vt = vo + at
16 = 0 + 4t
t = 4s
