Answer:
Answer to the following question is as follow.
Explanation:
Civil engineering industrial development projects have a significant influence on the environment, particularly in terms of excessive noise, environmental pollution, and land shrinkage.
Engineers have totally transformed our environment, from contemporary dwellings to bridges, space flight, automobiles, and cutting-edge mobile technologies. Engineers utilise their expertise to build new and exciting prospects and address any difficulties that may occur, and they employ their innovative ideas to accomplish so.
Answer:
a)
aB = 240 mm/s² (↓)
aA = - 345 mm/s²
b) For the Block C
v₀ = 130 mm/s
For the Block A
v₀ = - 43.33 mm/s
c) Δx = 727.5 mm
Explanation:
a) For the Block B
v = v₀ + a*t
480 = 0 + a*(2)
aB = 240 mm/s² (↓)
Then we have
3*LA + 4*LB + LC = L
If we apply
d(3*LA + 4*LB + LC)/dt = dL/dt
3*vA + 4*vB + vC = 0
d(3*vA + 4*vB + vC)/dt = d(0)/dt
3*aA + 4*aB + aC = 0
aA = - (4*aB + aC) / 3
aA = - (4*240 mm/s² + 75 mm/s²) / 3
aA = - 345 mm/s²
b) For the Block C
v = v₀ + a*t
v₀ = v – a*t
v₀ = 280 – (75)(2) = 130 mm/s
For the Block A
When t = 2 s
vB = 480 mm/s
vC = 280 mm/s
we use the formula
3*vA + 4*vB + vC = 0
3*vA + 4*(480) + 280 = 0
vA = - 733.33 mm/s
Now, we can apply
v = v₀ + a*t
- 733.33 mm/s = v₀ + (- 345 mm/s2)(2 s)
v₀ = - 43.33 mm/s
c) We can use the equation
Δx = v₀*t + (1/2)*a*t²
Δx = 130*(3) + (1/2)(75)(3)²
Δx = 727.5 mm
Answer:
The code is given below in python
# Code Block 1
count = 0 # count variable
total = 0 # total variable
enter = '' # input variable
while enter != 'stop':
enter = input('Enter a grade:' )
if enter != 'stop' and enter.isdigit():
total += int(enter) # add to total value
count = count + 1 # then to the count
print float(total) / count
# Code Block 2
numbers = []
while enter != 'stop':
enter = input('Enter a grade:' )
if enter != 'stop':
numbers.append(int(enter))
print sum(numbers) / float(len(numbers))
Everything wrong with 2020 is WW3 that dump trump decided to start , Australia fires , Kobe passed away than Pop smoke :( corona virus got really big , quarantine started , riots & protesting started because of that dumb who’re racist cop ! Hope this helps
