Answer:
T = 1.1285 10⁻² day
Explanation:
For this exercise the forces in the premiere are internal, so the angular momentum is conserved
L₀ = I₀ w₀
L = I w
L₀ = L
I₀ w₀ = I w
Angular velocity and period are related
w₀ = 2π / T₀
w = 2π / T
The moment of inertia of a sphere is
I₀ = 2/5 M R²
I = 2/5 m r²
If we assume that the mass of the star does not change in the transformation
We substitute
2/5 M R² 2π/T₀ = 2/5 M r² 2π/ T
R² /T₀ = r² / T
T = (r / R)² T₀
T = (6.1 / 2.0 104) 37
T = 1.1285 10⁻² day

Answer:
The distance traveled during its acceleration, d = 214.38 m
Explanation:
Given,
The object's acceleration, a = -6.8 m/s²
The initial speed of the object, u = 54 m/s
The final speed of the object, v = 0
The acceleration of the object is given by the formula,
a = (v - u) / t m/s²
∴ t = (v - u) / a
= (0 - 54) / (-6.8)
= 7.94 s
The average velocity of the object,
V = (54 + 0)/2
= 27 m/s
The displacement of the object,
d = V x t meter
= 27 x 7.94
= 214.38 m
Hence, the distance the object traveled during that acceleration is, a = 214.38 m
