You have to upload this in the area of mathematicians..!
It would be: Activation Energy = 300 KJ
Hope this helps!
Newton's 3rd law:
Every action has an equal and opposite reaction.
When you apply force on an object, there is an equal force applied on you from that object.
Answer:
3.1 m/s²
Explanation:
Apply Newton's second law:
∑F = ma
40 N = (13 kg) a
a ≈ 3.1 m/s²
Answer:
τsolid = 0.15 N•m
τhoop = 0.30 N•m
Explanation:
θ = ½αt²
α = 2θ/t² = 2(14)/8.3² = 0.406445 rad/s²
Solid disk I = ½mr² = ½(4.2)0.42² = 0.37044 kg•m²
τ = Iα = 0.37044(0.406445) = 0.150563... N•m
Hoop disk I = mr² = (4.2)0.42² = 0.74088 kg•m²
τ = Iα = 0.74088(0.406445) = 0.301127... N•m
