Tolong bantu saya, soal ada ada gambar
Jawaban:
1.
v = 2,2x10⁶ m/s
t = 1,5x10⁻¹⁶ s
radius/jari-jari r = ?
satu putaran 360⁰ = 2π
kecepatan sudut
ω = 2π/t
v = ω r
r = v/ω
r = vt/2π
r = 2,2x10⁶ x 1,5x10⁻¹⁶ /2π
r = 0,525x10⁻¹⁰ m
2.
v = 220 m/s
s = 700 km = 700000 m
t =?
v = s/t
t = s/v = 700000/220 = 3181,8 s = 3181,8/3600 = 0,88 jam
3.
v1 = 25 m/s
v2 = 31 m/s
v2' = v2-v1 = 31-25 = 6 m/s
