Tlong bikin diket serta cara sebuah mobil bergerak dg kelajuan awal 4 m/s menempuh jarak 96 m dlm waktu 16 sekon . tentukan a. perceptan mobil b. kecepatan mobil saat 16 sekon
newbie
V₀ = 4 m/s, x = 96 m, t = 16 s x = v₀ t + 1/2 a t² 96 = 4(16) + 1/2 a (16²) 96 - 64 = 128 a a = 32/128 = 0,25 m/s²
v = v₀ + a t = 4 + 0,25(16) = 4 + 4 = 8 m/s

A=v/t =4/16 =1/4 m/s v=s/t =96/16 =6 m/s
x = v₀ t + 1/2 a t²
96 = 4(16) + 1/2 a (16²)
96 - 64 = 128 a
a = 32/128 = 0,25 m/s²
v = v₀ + a t = 4 + 0,25(16) = 4 + 4 = 8 m/s
=4/16
=1/4 m/s
v=s/t
=96/16
=6 m/s
