Object #1 is very large; it has rings and many moons.
It's most likely the outer planet Saturn.
Object #2 is very small; it has no rings and a few moons but not many.
This one is most likely the inner planet Mars.
(3rd choice)
Assume that the deceleration due to braking is a ft/s².
Note that
40 mph = (40/60)*88 = 58.667 ft/s
25 mph = (25/60)*88 = 36.667 ft/s
The final velocity is zero when the car stops, therefore
v² - 2ad = 0, or d = v²/(2a)
where
v = initial speed
a = deceleration
d = stopping distance.
The stopping distance, d₄₀, at 40 mph is
d₄₀ = 58.667²/(2a)
The stopping distance, d₂₅, at 25 mph is
d₂₅ = 36.667²/(2a)
Therefore
d₄₀/d₂₅ = 58.667²/(2a) ÷ 36.667²/(2a)
= (58.667/36.667)²
= 2.56
Answer:
The stopping distance at 40 mph is 2.56 times the stopping distance at 25 mph.
Answer:
True
Explanation:
I guess you made a mistake on question.
but I understood what you wanted to say.
Hope this helps... :)
Ptotal=Ptotal —> m1v1+m2v2=m1v1’+m2v2’ —> (1kg)(2m/s)+(1kg)(0m/s)=(1kg)(-1m/s)+(1kg)(v2’) —> v2’=3m/s
answer: v=3m/s
Answer:
Noise making has led to loss on hearing.
Explanation:
Supposing you like engaging in parties because of the noise of the sound system it can cause loss on hearing if continued for long
