Answer:

Explanation:
Force 1 
Force 2 
Acceleration at stage 2 
Generally the weight of the Craft W is given as
W= upward force(thrust)
Therefore

Answer:
Y = 3.39 x 10⁶ m
Explanation:
We will use Young's Double Slit formula here:

where,
Y = Fringe spacing = ?
λ = wavelength =
= 8 x 10⁵ m
L = screend distance = 4030 nm = 4.03 x 10⁻⁶ m
d = slit separation = 950 nm = 9.5 x 10⁻⁷ m
Therefore,

<u>Y = 3.39 x 10⁶ m</u>
second question: How many seconds after the first snowball
should you throw the second so that they
arrive on target at the same time?
Answer in units of s.
Answer:
Part 1: 28°
Part 2: 1.367
Explanation:
Part 1:
Given: 62°
Simple
θ = 90°- 62°
<u>θ = 28°</u>
Part 2:
Y-direction
Δy
![t_{1} =\frac{2[16.2sin(62)]}{9.8}](https://tex.z-dn.net/?f=t_%7B1%7D%20%3D%5Cfrac%7B2%5B16.2sin%2862%29%5D%7D%7B9.8%7D)

![0=[16.2sin(28)]t_{2}+1/2(-9.8)t_{2}^{2}](https://tex.z-dn.net/?f=0%3D%5B16.2sin%2828%29%5Dt_%7B2%7D%2B1%2F2%28-9.8%29t_%7B2%7D%5E%7B2%7D)
![t_{2} =\frac{2[16.2sin(28)]}{9.8}](https://tex.z-dn.net/?f=t_%7B2%7D%20%3D%5Cfrac%7B2%5B16.2sin%2828%29%5D%7D%7B9.8%7D)

<u>Δt= 1.367s</u>
Hope it helps :)
2x/ 9y^5 this is your answer
I think shock waves require more speed they travel at the speed of sound
