The angle of bank needed, measured from the vertical is 86.6⁰.
<h3>
Banking angle of the circular path</h3>
The angle of bank needed, measured from the vertical is calculated as follows;
v = √(rg tanθ)
where;
- v is the speed = 1440 km/h = 400 m/s
- r is radius of the curve = 960 m
- g is acceleration due to gravity
- θ is the banking angle
400² = (960 x 9.8 x tanθ)
tanθ = 400²(960 x 9.8)
tanθ = 17
θ = arc tan(17)
θ = 86.6⁰
Thus, the angle of bank needed, measured from the vertical is 86.6⁰.

Answer: w = 4.38rad/s
Therefore the initial speed is 4.38rad/s
Explanation:
Given;
Angular distance = 5.7rad
Time = 2.6sec
When moving at constant angular acceleration, the angular distance covered can be given as;
d = ((w0 + w1)/2)t .....1
Where d = angular distance = 5.7rad
w = initial angular speed
w1 = final angular speed = 0
t = time of change. = 2.6 s
Substituting to equation 1 we have;
5.7 = ((w+0)/2)×2.6
w = 5.7×2/2.6
w = 4.38rad/s
Therefore the initial speed is 4.38rad/s
Answer:
They break down rocks.
Explanation:
The rain is slightly acidic due to the presence of carbon dioxide. Power plants and automobiles produce gases such as sulfur dioxide and nitric oxide, which react with water vapor in the atmosphere to form acid rain. They help in weathering the rocks which makes up the Earth's crust.
