V=d*t
Since d=75km=75000m
t=1.5h=3600*1.5= 5400s
=>V=75000*5400
=405000000m/s=4.05*10^8m/s
Answer:
C
Explanation:
a parallel circuit because there is more than one path
I’m not sure I think if you google it it should pop up or go on quizlet sorry
Answer: 2500km/s
Explanation:
use equation wich conects distance and acceleration:
S=Vst+at²/2
Vs=0km/s(from rest)
S=at²/2
S2=at²
t=√2S/a
t=√2*125km/25000 km/s²
t=0.1s
Vf --final velocity
Vs-- start velocity
a=Vf-Vs/t
at=Vf-Vs
Vs=0Km/s
at=Vf
25000Km/s*0.1s=Vf
Vf=2500Km/s
