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:
4.2·10⁷
Explanation:
Exponents are added when multiplying:
(a^b)(a^c) = a^(b+c)
1.15·10⁵ × 3.65·10² ≈ 4.2·10⁷

Your calculator is designed to work with scientific notation. Scientific or graphing calculators can also display their output in scientific notation. A spreadsheet can also perform this calculation for you and display the result in the required format.
Calculators and spreadsheets sometimes use "E" in place of "×10^". That is, 4.2E7 means 4.2×10^7.
