<u>Given that;</u>
Rate of acceleration = 5 m/s²
Mass of object = 20kg
<u>Find:</u>
Force required
<u>Computation:</u>
Force = Mass × Acceleration
Force required = Rate of acceleration × Mass of object
Force required = 20 × 5
Force required = 100 N

Answer:
A. T₁ = 7.204 N
B. T₂ = 19.07 N
C. I = 0.011979 kg * m²
Explanation:
Given
m₁ = 2.02 kg , d = 0.120 m, m₂ = 3.06 kg, s = 1.17 m, t = 0.810s
The tension can be find using the conserved energy in each axis so:
∑Fₓ = T₁ = m₁ * a₁
∑Fy = m₂ * g - T₂ = m₂ * a₁
Now to find the acceleration can use the equation of Newton motion
s = v₁* t + ¹/₂ * a₁ * t ²
Solve to a'
a₁ = 2* s / t ² = 2 * 1.17 m / (0.810 s)²
a₁ = 3.566 m/s²
A).
T₁ = m₁ * a₁ = T₁ = 2.02 kg * 3.566 m/s²
T₁ = 7.204 N
B).
T₂ = m₂ *(g - a₁) = 3.06 kg *(9.8 - 3.566) m/s²
T₂ = 19.07 N
C).
Finally to find the moment of inertia use the equation
∑ T = (T₂ - T₁) * r = I * α
α = a₁ / r
I = (T₂ - T₁ )* r²/ a₁
I = ( 19.07 - 7.204)* (0.06 m)² / 3.566 m/s²
I = 0.011979 kg * m²
