BANTUIN CARI HASIL DONG
Seseorang mengendarai motor dengan kecepatan 72 km/jam mendekati mobil yang membunyikan sirene berfrekuensi 800hz. Jika frekuensi yang diterima oleh pengendara motor itu sebesar 820hz dan cepat rambat bunyi di udara 340 m/s. Tentukan kecepatan mobil itu beserta arahnya.

Menurut aku
Berarti diketahui
vp = 20m/s
fs = 800 hz
fp = 820 hz
v = 340m/s
vs = ?
karena fp > fs berarti (+)vp (-)vs
fp = (v+vp/v-vs) x fs
