Answer:
UY Scuti is slightly larger than VY Canis Majoris
Explanation:
These stars are millions of miles away and cannot be seen by the naked eye.
Beetlejuice is another large star that can be seen by the eye.
Vi=0
T=3.07s
D=46m
A=?
A=2(d)/t ^2
2(46)/3.07^2=9.8m/s^2
Answer:
.17Hz
Explanation:
The formula for frequency is f= 1/T , where T is the period.
f = 1/6 and 1/6 ≈ .17
Answer:
a = - 3.14[m/s^2]
Explanation:
To solve this problem we must use the following kinematic equation:
![v_{f} ^{2}= v_{o} ^{2}+2*a*dx\\where:\\v_{f} = final velocity = 0 [m/s]\\v_{o}= initial velocity = 48.8 [m/s]\\ a = acceleration [m/s^2]\\dx = displacement [m]\\](https://tex.z-dn.net/?f=v_%7Bf%7D%20%5E%7B2%7D%3D%20v_%7Bo%7D%20%5E%7B2%7D%2B2%2Aa%2Adx%5C%5Cwhere%3A%5C%5Cv_%7Bf%7D%20%3D%20final%20velocity%20%3D%200%20%5Bm%2Fs%5D%5C%5Cv_%7Bo%7D%3D%20initial%20velocity%20%3D%2048.8%20%5Bm%2Fs%5D%5C%5C%20a%20%3D%20acceleration%20%5Bm%2Fs%5E2%5D%5C%5Cdx%20%3D%20displacement%20%5Bm%5D%5C%5C)
Now replacing:
![0 = 48.8^{2}+2*a*(378.7) \\-2381.44 = 757.4*a\\a = -3.14[m/s^2]](https://tex.z-dn.net/?f=0%20%3D%2048.8%5E%7B2%7D%2B2%2Aa%2A%28378.7%29%20%5C%5C-2381.44%20%3D%20757.4%2Aa%5C%5Ca%20%3D%20-3.14%5Bm%2Fs%5E2%5D)
The negative sign means the vehicle slows down.
